DeutschRed Sea crisis
The Red Sea crisis[45][46] began on 19 October 2023, when the Iran-backed Ansar Allah (Houthi movement) in Yemen launched missiles and armed drones at Israel, demanding an end to the invasion of the Gaza Strip.[47][48] The Houthis have since seized and launched aerial attacks against dozens of merchant and naval vessels in the Red Sea, drawing hundreds of air strikes on missile sites and other targets by US and allied forces.[49] The crisis is linked to the Israel–Hamas war, the Iran–Israel proxy conflict, the Iran–United States proxy conflict, and the Yemeni crisis.[50]
The Houthi movement's militants, who oppose Yemen's internationally recognized government, have since 2014 controlled a considerable swath of the country's territory along the Red Sea. Shortly after the beginning of the Israel–Hamas war, the Hamas-allied group began to launch missiles and drones at Israel. Houthi militants have also fired on various countries' merchant vessels in the Red Sea, and particularly in the Bab-el-Mandeb—the southern maritime gateway to the Suez Canal of Egypt and therefore a chokepoint of the global economy. The group has declared that they will not stop until Israel ceases its war on Hamas.[47][51]
The Houthis says they consider any Israel-linked ship as a target,[52][53][54] including US and UK warships, but they have also indiscriminately attacked the ships of many nations.[55][56] From October 2023 to March 2024, the Houthis attacked more than 60 vessels in the Red Sea.[57] To avoid attack, hundreds of commercial vessels have been rerouted to sail around South Africa.[58]
The Houthis' Red Sea attacks have drawn a military response from a number of countries. In January 2024, the UN Security Council adopted Resolution 2722, condemning the Houthi attacks and affirming freedom of navigation.[57] The United States-led Operation Prosperity Guardian was launched to protect Red Sea shipping. Since 12 January, the US and UK have led coalition air and missile strikes against the Houthis, while other countries are independently patrolling the waters near Yemen, attacking Houthi vessels in the Red Sea.[59] Undaunted, in May, Yemeni Armed Forces Brigadier General Yahya Saree said, "We will target any ships heading to Israeli ports in the Mediterranean Sea in any area we are able to reach".[60]
Background
Houthis within Yemen
The Houthi movement is an Iran-backed Zaydi Shia Islamist militant organization that exercises de facto control over parts of Yemen, though it is not the country's internationally recognized government; the Houthi takeover in Yemen in 2014 resulted in the group's acquisition of the capital city of Sanaa, but the anti-Houthi Presidential Leadership Council remains recognized by the international community as Yemen's legitimate government.[61] After this conflict grew into an ongoing civil war, millions of residents were internally displaced, and a Saudi-led coalition responded by imposing a blockade of Yemen. These combined to shrink the economy by half and contributed to famine in Yemen since 2016, one of the worst in the world.[62][63][64]
The US military destroyed drones in Yemen's Houthi-held region and over the Red Sea due to perceived threats, exacerbating tensions in the conflict-ridden area. This comes amidst ongoing attacks by the Houthis and challenges to diplomatic efforts to end the Yemeni war.[65]
Houthis and the Israel–Hamas war
Following the Hamas-led attack on Israel on 7 October 2023, which triggered the Israel–Hamas war, numerous Iran-backed militant groups across the Middle East (including the Houthis) expressed support for the Palestinians and threatened to attack Israel. Houthi leader Abdul-Malik al-Houthi warned the United States against intervening in support of Israel, threatening that such an intervention would be met with retaliation by drone and missile strikes.[66] In order to end their attacks in the Red Sea, the Houthis demanded a ceasefire in the Israel–Hamas war and an end to the accompanying Israeli blockade of the Gaza Strip.[67][68][69]
Weapons used by Houthi militants
According to Armament Research Services, Houthi weapons are mostly of Russian, Chinese or Iranian origin.[70][71] They are known to use surface-to-surface missiles, artillery rockets, loitering munitions and unmanned aerial vehicles (UAVs).[72] They have several missiles and UAVs capable of reaching Israel from Yemen:
- Toufan – a surface-to-surface missile, with a range of 1,800 km (1,100 mi).[73]
- Cruise missiles – from the Iranian Soumar family, with strike ranges of about 2,000 km (1,200 mi).[73]
- Quds-2 missile – supposedly with a range of 1,350 km (840 mi) but made to strike Israel.[74]
- Samad-3 and Samad-4 – UAVs/loitering munitions with ranges of 1,800 km (1,100 mi) and further.[74]
- Wa'id drones – similar to Iran's Shahed 136, loitering munition with a range of 2,500 km (1,600 mi).[74]
- Naval drones - 7 metres (23 ft) unmanned surface vessels (USVs) laden with explosives.[75][76]

October 2023
On 19 October 2023, US officials said the United States Navy destroyer USS Carney shot down three land-attack cruise missiles and several drones heading toward Israel launched by the Houthis in Yemen. This was the first action by the US military to defend Israel since the outbreak of the war.[66] It was later reported that the ship shot down four cruise missiles and 15 drones.[78] Another missile was reportedly intercepted by Saudi Arabia.[79] More were intercepted by Israel's Arrow anti-ballistic missiles; others fell short of their targets or were intercepted by the Israeli Air Force and the French Navy.
On 27 October 2023 two loitering munitions were fired in a northerly direction from the southern Red Sea. According to Israel Defense Forces (IDF) officials, their target was Israel, but they did not cross the border from Egypt. Of the two drones, one fell short and hit a building adjacent to a hospital in Taba, Egypt, injuring six; the other was shot down near an electricity plant close to the town of Nuweiba, Egypt.[80][81][82] A Houthi official later made a one-word post on Twitter after the drone crashed in Taba, mentioning the nearby Israeli city of Eilat.[83]
On 31 October an alert was triggered in Eilat, Eilot kibbutz and the Shahorit industrial park area regarding the penetration of hostile aircraft from the Red Sea. The aircraft was successfully intercepted over the Red Sea. The Arrow system intercepted a ballistic missile and the Air Force intercepted several cruise missiles fired from the Red Sea toward Eilat. The Houthis took responsibility for the launches.[84] One cruise missile was shot down by an F-35i Adir jet.[85] The downing of the missile by the Arrow system marks the first time it has been used in the Israel–Hamas war.[86] According to Israeli officials, the interception occurred above Earth's atmosphere above the Negev Desert, making it the first instance of space warfare in history.[87]
November 2023
On 1 November at 00:45 the IDF intercepted an air threat fired from Yemen and identified south of Eilat.[88] A US MQ-9 Reaper drone was shot down off the coast of Yemen by Houthi air defences on 8 November; the Pentagon previously said that MQ-9 drones were flying over Gaza in an intelligence gathering role to aid in the hostage recovery efforts.[89] On 9 November, the Houthis fired a missile toward the city of Eilat.[90] The missile was intercepted by an Arrow 3 missile, marking the first time it was used in an interception.[91]
On 14 November the Houthis fired numerous missiles, one of which was aimed toward the city of Eilat. The missile was intercepted by an Arrow missile according to Israeli officials.[92] The following day, US officials said that USS Thomas Hudner shot down a drone, fired from Yemen, that was headed toward it.[93] On 22 November, the Houthis fired a cruise missile aimed toward the city of Eilat. Israeli officials said the missile was successfully shot down by an F-35.[94] On 23 November 2023, US officials said that the destroyer USS Thomas Hudner had shot down several attack drones launched from Yemen.[95]
On 29 November 2023 US officials said the US Navy destroyer USS Carney shot down a Houthi KAS-04 drone as the destroyer approached the Bab-el-Mandeb Strait.[96] On 30 November 2023, Saudi media reported that an Israeli airstrike caused an explosion at a Houthi arms depot in Sana'a, the capital of Yemen. Houthi officials denied the report, stating that a gas station was hit instead. A member of the Houthis' political bureau, Hezam al-Asad, said that the explosion was caused by the remnants of a bomb left over from the Yemeni civil war.[97][98]
December 2023
On 6 December 2023, the Houthi movement launched several ballistic missiles at Israeli military posts in Eilat. On the same day, USS Mason shot down a drone launched from Yemen. There were no clear indications of its target.[99]
On 10 December 2023, the French Navy's frigate Languedoc, operating in the Red Sea, intercepted two drones launched from Hodeida, a Houthi-held port.[100] On 11 December 2023, the Norwegian oil tanker Strinda, fell victim to an overnight air attack, causing a fire on board.[101] The Languedoc intervened once again, intercepted a Houthi drone targeting the damaged tanker and subsequently placed itself in the protection of the vessel, preventing further attacks. The fire was brought under control and no injuries were reported. The vessel was then escorted to the Gulf of Aden out of the threat zone by an American destroyer, USS Mason.[102][103] The US Navy reportedly shot down 14 drones on 16 December 2023,[104] while Egyptian Air Defense Forces intercepted an object flying near Dahab.[105]
On 14 December 2023, India initiated Operation Sankalp to ensure the security of the regional maritime domain.[106] The destroyer INS Kolkata was stationed in the Gulf of Aden for maritime security on 18 December. The destroyer INS Kochi was already deployed in the region to counter Somali pirates, although the Government of India remains silent about its involvement in Operation Prosperity Guardian.[18]
By 21 December 2023, the port of Eilat, which gives Israel via the Red Sea its only easy shipping access to Asia without the need to transit the Suez Canal, had seen an 85% drop in activity due to the Houthi action.[107]
On 26 December 2023, Houthis said they carried out drone attacks on Eilat and other parts of Israel.[108] The US shot down 12 drones and 5 missiles fired by them, and the IDF said they also shot down a projectile launched from Yemen, targeting Israel, over the Red Sea, off the coast of the Sinai Peninsula.[109] On 26 December, India deployed the destroyers INS Mormugao and Visakhapatnam in the Arabian Sea after an Israel-affiliated merchant vessel was struck off the Indian coast. The navy was investigating the nature of the attack on the vessel, MV Chem Pluto, which docked in Mumbai on Monday, and initial reports pointed to a drone attack, a navy statement said. The Pentagon said on Saturday that a drone launched from Iran struck the Chem Pluto in the Indian Ocean. The Foreign Ministry of Iran denied the US accusations and called them "baseless". The vessel's crew included 21 Indians and 1 Vietnamese citizen.[110][111][112]
January 2024
On 4 January, just hours after the warning, Houthis launched an unmanned surface vessel (USV) towards US Navy and commercial vessels, but it detonated well over 1 nautical mile (1.9 km; 1.2 mi) from the ships.[113]
On 7 January, the Houthi movement stated that retaliatory attacks against the US Navy would continue unless the US hands over the Navy servicemembers who killed the 10 Houthi attack boat personnel for them to stand trial in Yemen.[114] On 7 January, the Pakistan Navy deployed two Tughril-class frigates, PNS Tughril and Taimur in the Arabian Sea following "recent incidents of maritime security."[citation needed]
On 10 January, a large-scale attack was initiated by the Houthis against USS Dwight D. Eisenhower, USS Gravely, USS Laboon, USS Mason and HMS Diamond, in which at least 21 UAVs and missiles were launched.[115]
On 11 January, US Navy SEALs raided a ship off the coast of Somalia which was bound to Houthi militants. Iranian-made missile components and other weapons, including air defense parts, were seized from the ship. The ship was then sunk and its crew of 14 people were detained. During the raid, a SEAL was pushed into the water by high waves and one of his teammates jumped in after him, causing both of them to go missing.[116][117] Both SEALs were declared dead by the US military after a 10-day search failed to locate them.[29]
On 12 January, the US and UK conducted airstrikes against over a dozen Houthi targets in Yemen with the support of multiple other countries,[118][119] just hours after the group's leader vowed that any American attack on its forces would "not go without a response".[120] The strikes were the first time Houthi targets in Yemen were targeted since the beginning of the Red Sea crisis.[121] More than 150 munitions and Tomahawk missiles struck 28 locations within Houthi-controlled areas. The Houthis said five of their fighters were killed and six others were injured.[122] A day later, the US performed another strike on a Houthi radar site in Sanaa.[123] On 14 January, American and British airstrikes were reported in Hodeida, and spy planes were reportedly spotted near the area. Reports also suggested that Israel was involved in the attacks.[124][125] The US issued a denial the same day.[126]
On 14 January, Houthis fired an anti-ship cruise missile from Hodeida in the direction of USS Laboon. The missile was shot down by a fighter jet before it could cause damage.[127]
On 16 January, the US struck four Houthi anti-ship ballistic missiles as they were being prepared to target ships in the Red Sea.[128] The following day, a fourth round of US strikes hit 14 missiles across Houthi-controlled areas.[129][130] On 22 January, in the eighth round of strikes against Houthis, the US and UK conducted airstrikes against eight Houthi targets in the vicinity of Sanaa airfield.[131][132]
On 21 January 2024, the French frigate Alsace joined defence operations in the Red Sea after transitting through the Suez Canal, reinforcing French assets deployed in the area in the face of Houthi attacks against international shipping.[133][134][135]
On 24 January, Houthi claimed to have attacked US destroyers and other warships in the Red Sea. This attack supposed to be in response to Operation Poseidon Archer. Houthi claimed to have directly hit a US destroyer with a missile during the attack.[136][better source needed] This attack was denied by the United States government.[137]
On the night of 26 to 27 January, the French frigate Alsace came to the aid of an oil tanker on fire in the Gulf of Aden, alongside Indian and American destroyers INS Visakhapatnam and USS Carney. The fire suffered by the Marlin Luanda tanker was caused by a missile fired from Yemen. It was brought under control after 20 hours, with no casualties sustained.[138][135]
On 29 January, Danish frigate HDMS Iver Huitfeldt departed from the Korsør naval base for the Red Sea to assist the US-led coalition in safeguarding commercial traffic against Houthi attacks.[139] On 31 January, top European Union diplomat Josep Borrell announced that the bloc plans to start a naval mission to protect merchant shipping in the Red Sea within the following three weeks, and officials stated that seven EU member states were prepared to provide military equipment.[140] An adviser to Borrell stated that the mission's launch date should be 19 February. Borrell added that the mission would be called 'Aspides', which translates to 'protector'.[141]
February 2024
On 2 February, the Houthis claimed that they had fired a ballistic missile towards Eilat. The IDF also said that the Arrow defense system intercepted a missile over the Red Sea.[142] On 3 February, a day after conducting airstrikes in Iraq and Syria, the US and UK conducted strikes against 36 Houthi sites, which included underground facilities, UAV storage and operation sites, missile systems, radars, and helicopters in 13 different locations across Houthi-controlled parts of Yemen in an attempt to degrade their capabilities. Houthi official Mohammed Al-Bukhaiti stated that they would "meet escalation with escalation" in response to the bombings.[143]
On 8 February, the German frigate Hessen departed from Wilhelmshaven for the Red Sea with about 240 people on board in order to assist the upcoming EU mission.[144]
On 10 February, Houthi official media listed the names of 17 fighters that were killed during joint US–UK strikes. The announcement came following public funerals held in Sanaa.[145]
On 15 February, the US Army announced that the Coast Guard seized a vessel originating from Iran and was bound for Houthi-controlled Yemen on 28 January. The US Army said the vessel was carrying advanced weapons and other "lethal aid". It had more than 200 packages containing ballistic missile and naval drone components, explosives, communications gear, and anti-tank missile launcher parts.[146]
On 19 February, the European Union announced the start of the naval mission Operation Aspides, which plans to send warships and provide early airborne warning systems to the Red Sea and surrounding waters. The launch was confirmed by Italian Foreign Affairs Minister Antonio Tajani. France, Germany, Italy and Belgium all announced their intention to contribute to the operation. Operation Aspides will be headquartered in Larissa, Greece. The operation is not allowed to attack pre-emptively, and will only fire on Houthis if they attack first.[147] The operation will only operate at sea, and will not conduct or participate in military strikes.[148] The same day, Houthis claimed they shot down an MQ-9 Reaper drone over the Red Sea. US officials confirmed the incident, adding that the drone belonged to the US Air Force and crashed off the coast of Hodeidah.[149]
On 20 February, France announced that one of its warships shot down two Houthi UAVs over the Red Sea, while CENTCOM announced the downing of ten bomb-carrying drones and a cruise missile targeting the USS Laboon.[150] Houthis claimed that they attacked Eilat and a number of American warships in the Red Sea and Arabian Sea with drones.[151]
On the morning of 22 February, two UAVs targeting commercial vessels in the Red Sea were stated to have been intercepted yet again by one of the French FREMM frigates in the area.[152][153] Later that day, the Houthis' Humanitarian Operations Coordination Center sent statements to shipping insurers and firms announcing a formal ban on vessels owned or partially owned by Israeli, British, or American entities or individuals in the Red Sea, Gulf of Aden, and Arabian Sea. The ban also included vessels sailing under the flags of the mentioned nations.[154][155] The statement came as the Houthis launched drones and ballistic missiles targeting Eilat and an American destroyer in the Red Sea, though none of them struck their target according to authorities. However, the Houthis successfully fired two missiles at a Palau-flagged cargo ship named Islander which sparked a fire and wounded one sailor on board the vessel, though the ship continued its transportation route.[156] Houthi leader Abdul-Malik al-Houthi also said in a statement that operations in the Red Sea and surrounding waters were continuing, escalating and effective, and announced the introduction of "submarine weapons" without giving further details.[157]
On 24 February, the US and UK conducted their fourth round of joint airstrikes, hitting 18 Houthi targets across eight locations. The British Ministry of Defense said that four Royal Air Force Typhoon fighter jets, supported by two Voyager tankers, participated in the strikes.[158] The Houthis' official news agency said the attacks killed a civilian and injured eight others, making them the first civilian casualties during US and British airstrikes.[159]
On 26 February, damages were reported to Red Sea undersea communications cables. Initial reports by industry sources, African press, and Israeli press, tied this to Houthi attacks that was predicted by international press, while Seacom was unable to confirm the cause, they later confirmed the location of the damage to be in Yemeni maritime jurisdictions.[160] Press releases by Seacom and Flag Telecom were describing the difficulty of repair due to the crisis in shipping.[161][162] Houthi leaders denied involvement.[163] The same day, Greece approved a decision to send the Greek frigate Hydra to the Red Sea to assist Operation Aspides.[164] Also on 26 February, the German frigate Hessen launched two SM-2 missiles at an American Reaper drone in a friendly fire incident. The missiles missed their target, falling into the sea.[165]
On 27 February, Houthi leader Mohammed al-Houthi said they will only allow a salvage operation to take place if humanitarian aid is sent to Gaza Strip.[166] On the same day, German frigate Hessen intercepted two Houthi drones as they targeted the naval vessel, making it the German Navy's first naval engagement of Operation Aspides.[167] The Hessen downed one drone with her 76mm cannon and a second with her CIWS system.[168] The Rubymar, which was struck by the Houthis earlier in February started sinking while drifting northwards[169] and sank by 2 March 2024.
March 2024
On 2 March, during Operation Aspides, the Italian destroyer Caio Duilio shot down a Houthi missile over the Red Sea. The missile was within 4 miles (6.4 km) of the destroyer before it was shot down.[170]
On 4 March, Houthi Telecommunications Minister Misfer Al-Numair said that vessels entering Yemeni waters would need a permit from the Houthi-controlled Maritime Affairs Authority.[171]
On 4 March 2024, INS Kolkata, deployed to the Gulf of Aden, responded to a request from MSC Sky II, a Liberian flagged container vessel, that had reportedly been attacked by a drone or missile, at about 1900 h (IST) on 4 March 24, 90 nm southeast of Aden. The ship's master reported smoke and flames onboard following the attack. INS Kolkata was quickly redirected to provide the required support, and by 2230 hours (IST), it had reached the incident site. The Kolkata then escorted the ship from the area of the incident into the territorial seas of Djibouti at the master's request. Early on 5 March, a 12-person specialised firefighting team from Kolkata boarded the Sky II and extinguished the remaining fires. In addition, an explosive ordnance disposal team boarded the Sky II to evaluate residual risk. The 23-person crew, 13 of whom were citizens of India, were safe, and the ship continued sailing towards its next destination.[172][173][174]
On 8 March, Finland announced they will send up to five officers to the European-led Operation Aspides and up to two soldiers to take part in the US-led Operation Prosperity Guardian.[175] The Royal Netherlands Navy also confirmed the same day that it would be sending the De Zeven Provinciën-class frigate HNLMS Tromp to the Red Sea. The frigate would be a part of Operation Prosperity Guardian but also support Operation Aspides. The frigate is manned with 200 sailors. She has a NH90 maritime attack helicopter on board and is equipped to intercept incoming missiles and drones. The Netherlands also announced its intent to send a joint logistics support vessel to the Red Sea in the following month.[176]
On 9 March, the French FREMM Alsace patrolling the Gulf of Aden under the newly-launched EU Aspides mission, as well as French Mirage 2000-5 stationed in Djibouti, intercepted 4 Houthi UAVs threatening commercial transit that day.[177]
On 11 March, the US and UK conducted 17 airstrikes against port cities and towns under Houthi control in Western Yemen. Among the targets struck were Hodeidah and the port of Ras Isa.

On 18 March, Yemeni Houthis launched a cruise missile that successfully struck Israel, reportedly hitting an open area north of Eilat. Israel stated there was no damage or injuries caused.[181]
On 20 March, the embarked Panther helicopter of the French FREMM Alsace shot down a Houthi UAV flying towards commercial vessels over the southern Red Sea. The door gunner of the helicopter, which was patrolling in the area, engaged and destroyed the UAV with a 7.62 mm machine gun.[182][183] The same day, a US Navy sailor assigned to the USS Mason went missing while conducting supporting operations in the Red Sea. On 23 March, the US Department of Defense declared him as dead, stating that his death occurred in a non-combat incident.[30]
On the morning of 21 March, the embarked helicopter of the German frigate Hessen destroyed a seaborne drone (USV) in the Red Sea. Later that day, the French FREMM Alsace, providing close protection to merchant shipping in the area, engaged and destroyed 3 Houthi ballistic missiles threatening the transit with its Aster 30 missiles.[184][185][186] The same day, Bloomberg had reported that the Houthis reached a deal with Russia and China, agreeing to provide safe passage for vessels under their jurisdiction in exchange for political support.[187] The IDF also announced on the same day that it intercepted a "suspicious aerial target" approaching Israeli territory over the Red Sea.[188]
On 27 March, the US Navy said it shot down four Houthi UAVs targeting warships in the Red Sea.[189] The following day, several Russian Pacific Fleet warships navigated into the Red Sea via the Bab al-Mandeb Strait, including the Russian cruiser Varyag and the Russian frigate Marshal Shaposhnikov according to Zvezda.[190][191] This was reportedly after the Houthis made a political deal with Russia and China, allowing them safe passage possibly in exchange for blocking resolutions at the UN Security Council.[192]
April 2024
On 3 April, Danish chief of defense Flemming Lentfer was fired after failing to report flaws regarding air defenses and weapons systems aboard the Ivar Huitfeldt frigate which emerged after a Houthi attack in March, when the frigate's air defenses failed while engaging with Houthis. A problem also occurred with the frigate's ammunition system, which caused half of the rounds it fired to detonate before hitting their target.[193]
In April, Tim Lenderking, the United States special envoy for Yemen, stated that he hoped to achieve a diplomatic solution with the Yemeni Houthis in regard to their attacks, and that the US would consider removing the Houthis from its designated terrorist list if they ceased their attacks.[194]
On 9 April, the IDF used a seaborne missile from the INS Magen to shoot down a UAV for the first time. The UAV, which came from the Red Sea, breached Israeli airspace and crossed into the area of the Gulf of Aqaba, setting off sirens in Eilat.[195][196]
On 10 April, the US military said it destroyed eleven drones belonging to the Houthis which it said presented a threat to US, coalition, and merchant vessels. Eight of the drones were destroyed in Houthi-controlled territory, while three were shot down; two over the Gulf of Aden and another over the Red Sea.[197]
On 13 April, the Houthis in coordination with Iran launched several drones at Israel amidst the Iranian strikes against Israel, according to the maritime security agency Ambrey. The organization said that the target of the drones are potentially Israeli ports, and that collateral damage to shipping is likely.[198] The following day, the IDF's C-Dome system intercepted an aerial target in the Eilat area, which came from the direction of the Red Sea.[199]
On 18 April, the Iranian spy ship MV Behshad, which is suspected of assisting the Houthis, left its position at sea and started to sail towards the port of Bandar Abbas.[200]
On 25 April, a Greek frigate intercepted two Houthi drones in the Red Sea.[201]
On 26 April, the Houthis said they shot down an American MQ-9 Reaper drone off the coast of Yemen. The US confirmed the crash of an MQ-9 Reaper in the area and launched an investigation into it.[202]
May 2024
In early May, Houthi-run Saba News Agency reported that at least 18 people were arrested on suspicions of spying for the US and Israel. According to Saba, the supposed spy network was formed in November. Saba did not provide evidence to support the claim, but said that the men had confessed to spying.[203]
On 7 May, USS Dwight D. Eisenhower returned to Red Sea after a short port call in late April at Souda Bay, Crete to resupply.[204]
On 10 May, a coalition warplane intercepted a Houthi drone over the Gulf of Aden. The following day, three other drones were intercepted over the Red Sea. No casualties or damage to shipping were reported in borh incidents.[205]
On 15 May, the Houthis claimed to have shot down a MQ-9 Reaper drone near Marib, later releasing footage of its purported downing. The US military however declined to comment.[206] On 21 May, the Houthis claimed to have shot down another MQ-9 Reaper drone, stating it crashed in Al Bayda Governorate.[207]
On 29 May, the Houthis claimed that they shot down an MQ-9 Reaper drone with a surface-to-air missile over Marib province. Footage obtained by the Associated Press displayed a damaged drone, however it remained mostly intact and lacked signs of blast damage. It also lacked markings, and the downing was not acknowledged by local authorities. Associated Press reported that a USAF official denied the loss of aircraft on the theater, meanwhile the CIA that operates those drones refused to comment.[208]
On 30 May, the US and UK conducted strikes against 13 Houthi targets across Yemen, killing 16 people and injuring at least 35 others.[209] The Houthis on the next day threatened to escalate their attacks in response and claimed to have targeted the USS Dwight D. Eisenhower with drones and ballistic missiles. An American defence official told The Associated Press that the ship was in fine condition.[210] The US Central Command meanwhile reported that the Houthis launched two anti-ship ballistic missiles and a drone over the Gulf of Aden, with the drone being intercepted and the missiles not causing any damage. In addition, it stated that they also launched four drones over the Red Sea, with three being intercepted and one crashing into the water.[211]
June 2024
The Houthis targeted the USS Dwight D. Eisenhower, USS Gravely, and three commercial vessels on 1 June. The US Central Command confirmed the attacks, while adding that no casualties or damage was reported, with one drone being intercepted in the southern Red Sea and two others crashing into the water. It also added that it had shot down two anti-ship ballistic missiles targeting USS Gravely.[212][213]
On 3 June, the IDF's Arrow defense system intercepted a surface-to-air missile aimed at Eilat from the direction of the Red Sea.[214] The Houthis later claimed that they were targeting an IDF site with a ballistic missile named Palestine.[215] On 6 June, the group and the Islamic Resistance in Iraq claimed to have launched two coordinated attacks on Haifa. Israel however denied these claims. The Houthis later stated that they would intensify their joint operations with the Islamic Resistance in Iraq.[216]
On 6 June, at least eleven Yemeni UN workers were arrested by the Houthis. Four days later, the group claimed that they had arrested an undisclosed number of members of an "American-Israeli spy network" that disguised itself as international and UN organizations, and aired purported confessions from ten Yemenis, claiming that several of them were recruited by the U.S. Embassy in Yemen. None of the people in the taped confessions however were among the UN workers arrested four days earlier.[217]
The Houthi-run Al-Masirah television channel on 7 June reported that the US and the UK had carried out four airstrikes on the Hodeida International Airport and the Port of Salif, in addition to two airstrikes on the al-Thawra region to the north of Sana'a.

Houthi attacks on commercial vessels
Iran-backed Houthi forces began attacking shipping vessels affiliated with Israel passing through the Red Sea on 19 November 2023. By February, 40 vessels had been attacked. Global shipping companies, which had typically sailed through the Red Sea, as well as the Suez Canal, instead moved to position their vessels around the Cape of Good Hope, off the Cape Peninsula, South Africa.[294][295][296][297]
Between November and December 2023, a 1.3 percent decrease in global trade resulted from Houthi attacks on commercial shipping in the Red Sea.[298] By March 2024, over 2,000 ships had diverted routes away from the Red Sea, making costlier voyages, since the first Houthi attack the previous November.[299]
Initial Houthi pledges to target any ship with links to Israel were followed by attacks on ships connected to over a dozen nations, as well, stated, in January 2024, as avenging "American-British aggression against our country". US Central Command responded that the Houthis attacks "have nothing to do with the conflict in Gaza" and that Houthis had "fired indiscriminately into the Red Sea", targeting ships, and impacting more than 40 nations.[300][301] On 3 May 2024, the Houthi-aligned Yemeni Armed Forces SPC military spokesperson Yahya Saree announced, in a televised speech, that "We will target any ships heading to Israeli ports in the Mediterranean Sea in any area we are able to reach".[60]
First and second phases (November – December 2023)
On 19 November 2023, Houthi forces used a Mil Mi-17 helicopter to board and seize the car transporter Galaxy Leader, which was en route to India with 25 people but no cargo on board.[302][303] The incident followed a statement by Houthi spokesman Yahya Saree on the group's Telegram channel, declaring their intention to target ships owned or operated by Israeli companies or carrying the Israeli flag.[304] According to the ship's owner, the vessel was then moved to the Yemeni port of Hodeidah.[305] Sarea also urged countries to remove their citizens from crews of such ships. Earlier, Houthi leader Abdul-Malik al-Houthi had threatened further attacks against Israeli interests, including potential targets in the Red Sea and the Bab-el-Mandeb Strait. His speech emphasized the group's capability to monitor and target Israeli ships in these regions.[306]
On 24 November, Iran allegedly attacked CMA CGM Symi, a Malta-flagged container ship in the Indian Ocean.[307] A drone was shot down over the Red Sea by an IDF fighter jet.[308]
On 26 November, the Liberian-flagged MV Central Park, an oil tanker managed by Zodiac Maritime, was seized off the coast of Yemen in the Gulf of Aden. It carried a full cargo of phosphoric acid with 22 crew members consisting of Russian, Vietnamese, Bulgarian, Indian, Georgian and Filipino nationals.[309] The destroyer USS Mason, along with a partner country in the multilateral anti-piracy operation CTF 151, conducted a visit, board, search, and seizure (VBSS) operation that facilitated the release of the Central Park and captured the hijackers on the ship following their attempted escape. The ship's crew was unharmed. The US military reported that in the early morning hours of the following day, two ballistic missiles were fired in the direction of the Mason and the Central Park from Houthi territory in Yemen and ended up in the Gulf of Aden.[310][311] The five hijackers, all suspected Somali pirates, were detained by the US Navy.[311][312]
On 3 December, the United States Navy Arleigh Burke-class destroyer USS Carney reportedly shot down three attack drones launched from Yemen that were approaching the ship. After shooting down the drones, the ship responded to a distress call by three commercial ships in the area (the Unity Explorer, Number 9 and Sophie II) which were under attack by ballistic missiles launched from Yemen.[313]
The Houthis claimed responsibility for two of the attacks. Houthi military spokesman Brigadier General Yahya Saree stated that one merchant vessel was hit by a missile and another by a drone while in the Bab el-Mandeb strait, without mentioning a warship.[313] A Pentagon source said that the attacks on Carney caused no injuries or damage.[314]
Third phase (December 2023 – May 2024)
On 9 December 2023, the Houthis vowed to target any vessel en route to Israeli ports, entering the third phase of the crisis. Following the announcement, the frequency of attacks around the Bab-el-Mandeb increased.[315]
On 12 December, the Houthis launched an anti-ship cruise missile attack against the Norwegian commercial ship Strinda, an oil and chemical tanker operated by the J. Ludwig Mowinckels Rederi company, while it was close to the Bab-el-Mandeb. The Strinda was on its way from Malaysia to Italy (via the Suez Canal). The attack caused a fire aboard the ship; no crew members were injured.[316][317] The ship was carrying cargo of palm oil. The French Armed Forces Ministry and US Department of Defense reported that the Languedoc shot down a drone targeted at the Strinda, and USS Mason also rendered aid. The Houthi attack on the Strinda was an expansion of its series of attacks against maritime shipping in the strait; the Houthis began to attack commercial vessels without any discernible tie to Israel.[317][49]
On 13 December, Houthi rebels attempted to board the Ardmore Encounter, a Marshall Islands-flagged commercial tanker coming from Mangaluru, India and en route to either Rotterdam, Netherlands or Gävle, Sweden, but failed, prompting a distress call from the ship. They then targeted the tanker with missiles, which missed. USS Mason responded to the tanker's distress call and shot down a UAV launched from a Houthi-controlled area. The Ardmore Encounter was able to continue its voyage without further incident.[318]
On 14 December, a Houthi-launched missile was fired at the Maersk Gibraltar, though it missed its target.[319] On 15 December, Houthi spokesperson Yahya Sarea claimed responsibility for attacks on two Liberian-flagged vessels identified as MSC Alanya and MSC Palatium III. The Houthis fired naval missiles at the ships as they alleged they were traveling to Israel.[320]
On 15 December, it was reported that the Liberian-flagged Al-Jasrah, which is owned by Hapag Lloyd, caught fire after being hit by a Houthi-launched projectile while sailing through the Bab el-Mandeb Strait.[321] On 16 December, Royal Navy destroyer HMS Diamond shot down a drone over the Red Sea while it was targeting a commercial ship.[15]
On 18 December, Houthis claimed to have launched attacks targeting two cargo vessels in the Red Sea near Mocha port, the MSC Clara and the Norwegian-owned Swan Atlantic. The Swan Atlantic's owner, Inventor Chemical Tankers, said its water tank was damaged in the attack and denied it has any Israeli ties.[322]
On 23 December, Houthis fired two anti-ship ballistic missiles into the southern Red Sea, but no ships were hit. USS Laboon also shot down four UAVs that were heading toward it.[323]
On 26 December, Houthis fired several naval missiles at the MSC United VIII in the Red Sea after it rejected three warning calls.[108] She reported several explosions near her.[324][325] She alerted a nearby coalition task force warship and engaged in evasive maneuvers as per her instructions during the attacks.[326][327]
The container ship Maersk Hangzhou, owned by A.P. Moller Singapore Pte. Ltd. and in service with Maersk Line, was attacked over two days in late December. On 30 December, she was hit by a land-based missile, suffering only limited damage and no casualties. The following day, four small Yemeni gunboats attempted to attack and board the ship. The Maersk Hangzhou's own security team repelled them. Responding to her distress call, helicopters were deployed from USS Dwight D. Eisenhower and USS Gravely, which were then engaged by the Houthis. They returned fire and sank three of the boats, killing their crews (ten militants in all—the fourth boat withdrew), thus inflicting the first known casualties of the Red Sea crisis.[328]
On 11 January 2024, Houthis fired an anti-ship ballistic missile into international shipping lanes in the Gulf of Aden, which landed in the water near a commercial vessel, causing no damage or injuries.[329]
On 12 January, Houthis mistakenly targeted MT Khalissa as it carried Russian crude oil based on outdated information linking it to the United Kingdom.[330] A missile was fired near the vessel as it sailed off the coast of Aden, causing no injuries or damage. Three small boats also tailed the vessel for over an hour.[331][332]
On 15 January, Houthis struck MV Gibraltar Eagle with an anti-ship missile, causing a small fire on board. The attack did not cause injuries or significant damage. Another missile fired earlier failed in flight and crashed in Yemen.[333]
On 16 January, an anti-ship ballistic missile fired by the Houthis struck MV Zografia, causing material damage but no injuries. The Greek-owned and Malta-flagged vessel, which came from Vietnam and was en route to Israel, was able to continue transiting the Red Sea.[334][335]
On 17 January, Houthis struck the US-owned bulk carrier MV Genco Picardy with a drone while it traversed the Gulf of Aden, causing minimal damage and no injuries to the crew.[336][337] The Indian Navy announced the following day that INS Visakhapatnam was diverted to rescue the ship's crew of 22 people. No casualties were reported and the ship later continued onwards for its scheduled journey.[338][339]
On 18 January, Houthis launched two anti-ship ballistic missiles at MV Chem Ranger, which was traveling from Jeddah, Saudi Arabia to Kuwait. The missiles landed in the water near the ship while it was traversing through the Gulf of Aden, and there was no reported damage or injuries. However, a Houthi post on social media claimed that they launched several naval missiles at the vessel, resulting in direct hits.[340]
On 22 January, Houthis claimed they attacked the US military cargo ship MV Ocean Jazz, but did not state the location of the attack or if damage was caused. However, the claim was rejected by the US Naval Forces Central Command.[341]
On 24 January, a Houthi missile exploded on the sea about 100 metres off the starboard side of the US-flagged, -owned, and -operated container ship Maersk Detroit. This ship and the Maersk Chesapeake, both in the US Maritime Administration's Maritime Security Program and Voluntary Intermodal Sealift Agreement were carrying US Department of Defense, US Department of State, USAID, and other US government agency cargo from Oman, and accompanied by US naval vessels while they were near the Bab el-Mandeb Strait transiting north. Two other missiles were shot down by USS Gravely. Following the incident, the two vessels were ordered back to the Gulf of Aden by US Navy instruction with Navy escort and Maersk Line Limited, a subsidiary that sails primarily US government-owned goods, suspended all sailings in the Red Sea.[342][343][344]
On 26 January, a Houthi ballistic missile fired toward USS Carney was shot down.[345] The same day, the Marlin Luanda, an oil tanker operated by British company Oceonix Services on behalf of Trafigura, carrying Russian-produced naphtha, was hit by a missile as it traversed the Gulf of Aden 60 nautical miles (110 km; 69 mi) southeast of Aden, according to UK Maritime Trade Operations. A Houthi spokesperson said the ship was targeted in response to "American-British aggression against our country". The missile set fire to a starboard cargo tank, which was extinguished by the crew without injury.[300][346]
On 28 January, HMS Diamond intercepted a Houthi drone targeting it.[347] The following day, Houthis claimed they struck USS Lewis B. Puller with a missile in the Gulf of Aden. An American defense official rejected the claim.[348] The UKMTO reported the same day that a merchant vessel was suspiciously approached by three small boats, who got as close as one nautical mile, 44 nautical miles (81 km; 51 mi) west of Al-Mukha. The merchant vessel's security crew fired warning shots to deter the small boats, and the vessel was able to safely proceed to its next port of call.[349]
On 30 January, a Houthi missile targeting USS Gravely came within a mile of the naval vessel before being intercepted, the closest any Houthi attack had yet come to a US warship.[350] The following day, the Houthis claimed they targeted an American merchant ship named Koi with several naval missiles. The security firm Ambrey said the same day that a merchant vessel reported an explosion on its starboard side 69 nautical miles (128 km; 79 mi) southwest of Aden, but it was not stated if it was the Koi.[351] USS Carney also shot down three Iranian drones and one Houthi missile over the Gulf of Aden.[352]
On 6 February, Houthis claimed they hit a British and an American ship in the Red Sea, which they identified as the Morning Tide and Star Nasia, respectively. Neither ship received major damage. Ambrey reported that a Barbados-flagged British ship received minor damage to its port 57 nautical miles (106 km; 66 mi) from the coast of Hodeidah, and the UKMTO said that it also received reports that the port side of a ship was struck by a projectile west of Hodeidah and a small craft was seen nearby.[353] The second ship, which the UKMTO identified as a Marshall Islands-flagged, Greek-owned vessel originating from the US and en route to India, was attacked off the coast of Aden. It reported an explosion 50 metres off its starboard side.[354]
On 12 February, Houthis fired two missiles at the Star Iris as it traveled south of the Bab el-Mandeb strait, claiming it was an American vessel without providing evidence. The attack caused minor damage to the vessel, but no injuries were reported. The Star Iris came from Brazil and was en route to Bandar Khomeini, Iran. It was able to proceed to its next port of call.[355]
On 16 February, the UKMTO reported that a missile lightly damaged a Panama-flagged ship off the coast of Mokha.[356] Houthis later claimed responsibility for the attack, identifying the tanker as the Pollux and claiming they targeted it with a "large number of appropriate naval missiles". The US Department of State said the tanker was bound for India and was struck on its port side by a missile fired from Yemen.[357]
On 18 February, the Belize-flagged cargo ship MV Rubymar was attacked in the Bab el-Mandeb strait as she sailed from Khor Fakkan, UAE, to Varna, Bulgaria. Saree said the attack caused catastrophic damage to the vessel, forced her to stop, and put her at risk of sinking. The vessel's crew evacuated after the attack. Ambrey said the attack made the ship briefly slow down and deviate from her course, before contacting the Djiboutian Navy and returning to her previous course and speed. The vessel remained afloat as of 8 am London time. CENTCOM said the attack on the Rubymar caused her to slowly take in water and leave behind a 29-kilometre (18 mi) oil slick, causing an environmental disaster. It added that she was carrying 41,000 tonnes of fertilizer, which could spill into the sea if she were to sink.[358] On 2 March, the Yemeni government reported that the Rubymar had sunk.[43]
On 19 February, a Greece-flagged bulk carrier requested military assistance after a missile attack east of Aden.[359] Houthis claimed responsibility for the attack, identifying the vessel as the Sea Champion. They added that another vessel called Navis Fortuna was also struck.[360]
On 22 February, Houthis fired two missiles at the cargo ship MV Islander as she traversed the Red Sea, causing a fire. CENTCOM announced that damage was done to the vessel and one person suffered minor injuries as a result of the attacks.[361]
On 6 March, the Houthis struck the Barbados-flagged bulk carrier True Confidence with an anti-ship missile, igniting a fire and leading the crew to abandon the vessel. Three crew members were killed and four others sustained serious burns from the fire.[362] INS Kolkata handled the situation. The event happened 55 nautical miles to the southwest of Aden. INS Kolkata deployed its boats and onboard helicopter to reach the location and deployed life rafts to save 21 crew members, one of whom was Indian. The ship's medical professionals provided vital medical attention to the injured crew members.[363][364]
On 8 March, the Houthis launched a large attack on US warships and commercial shipping, firing two anti-ship missiles at the Singapore-flagged bulk carrier MV Propel Fortune and 37 drones at American naval vessels.[365] A French warship and fighter jets shot down four drones approaching vessels belonging to Operation Aspides; the Danish frigate Iver Huitfeldt shot down another four; and the US Navy intercepted another 15.[366][367]
On 14 March, reports that missiles had struck the Panama-flagged Pacific 01 in the Gulf of Aden were debunked.[368][369] The following day, Houthis threatened to expand attacks to include Israel-linked vessels passing through the Indian Ocean towards the Cape of Good Hope.[370] On the same day, Yahya Saree claimed that Houthi forces launched drones and anti-ship missiles at American and Israeli vessels in the Indian Ocean, while also targeting US naval vessels with drones.[371]
On 24 March, Houthis targeted the Chinese-owned and Panama-flagged oil tanker MV Huang Pu with six anti-ship ballistic missiles as she was en route to New Mangalore Port, India.[372] One of the missiles landed in Yemen, while four others struck in the vicinity of the vessel and the fifth directly struck her, causing a fire which was extinguished thirty minutes later. She was carrying Russian crude oil at the time of the attack,[373] and was previously owned by a British shipping firm.[374][375]
On 7 April, the Houthis claimed responsibility for attacks on three commercial vessels and two US frigates in the Red Sea and Indian Ocean. They identified the commercial vessels as the British-owned, Marshall Islands-flagged Hope Island and the Israeli-owned, Panama-flagged MSC Grace F and MSC Gina.[376][377][378]
On 9 April, the Maersk Yorktown, a US-flagged and owned container ship which was being escorted by the destroyers USS Mason and USS Laboon at the time, was targeted by an anti-ship missile while traversing the Gulf of Aden. The missile was intercepted before it could cause damage.[379] The following day, the Houthis claimed responsibility for the attack on the Yorktown and announced that they targeted the vessels MSC Gina and MSC Darwin, which they claimed were Israeli, and a US destroyer in the Gulf of Aden.[380]
On 24 April, Maersk Yorktown was again[379] targeted while underway the Gulf of Aden, along with the Madeira-flagged, Swiss-owned MSC Veracruz. Each was attacked in the Indian Ocean by Iranian-backed Houthi militants.[381]
On 26 April, two Houthi missiles hit the Panama-flagged oil tanker Andromeda Star, causing minor damage, approximately 15 nautical miles (28 km; 17 mi) southwest of Mokha.[382] The Houthis claimed she was a British oil ship. She had been carrying Russian oil from Primorsk, Russia to Vadinar, India.[383] INS Kochi rescued 30 crew members onboard the ship. An official reconnaissance was conducted by a helicopter after which the explosive ordnance disposal (EOD) reached the vessel to "residual risk assessment". Later the ship continued towards her next destination.[384][385] Another missile landed in close proximity to the nearby Antigua and Barbuda-flagged MV Maisha, causing no damage.[386]
On 29 April, Houthis attacked the Malta-flagged merchant vessel MV Cyclades with anti-ship missiles and UAVs, causing minor damage.[387] The Houthis also claimed responsibility for a drone attack on the Portugal-flagged MSC Orion that day, directly striking her around 600 kilometres (370 mi) off the coast of Yemen while she was in the Arabian Sea, making it the furthest attack by the Houthis so far.[388][389] In response to the increased range, the EU's Operation Atalanta advised for an alternative shipping route to be established at least 150 nautical miles (280 km; 170 mi) east of the current route.[390]
Fourth phase (May – July 2024)
In early May 2024, in what he described as the "fourth stage" of the attacks, Houthi leader Abdul Malik al-Houthi vowed to attack ships of any company related to Israel or carrying goods for Israel in response to Israel's Rafah offensive in southern Gaza.[391]
On 9 May, the Houthis claimed responsibility for attacks on three Panama-flagged container ships. In the first attack, two explosions were reported near a ship in the morning of 7 May. The Houthis said that the explosions were missile attacks targeting MSC Gina and MSC Diego.

The Houthis targeted a commercial ship in the Gulf of Aden on 21 June according to the UKMTO center said and the Joint Maritime Information Cente, with no casualties or damage being reported.[234] The Houthis on the next day identified it as the Liberian-flagged bulk carrier Transworld Navigator and stated that they had targeted it with ballistic missiles.[412] They also claimed to have targeted the Shorthorn Express in the Mediterranean Sea, but there was no independent confirmation of the attack.[236]
The Houthis targeted the Transworld Navigator again on 23 June using a USV in the Red Sea, with the crew reporting minor injuries and moderate damage to the ship. The group also claimed to have targeted the Stolt Sequoia in the Indian Ocean with cruise missiles.[413][414] The Liberian-flagged container ship MSC Sarah V reported a missile attack near it on 24 June while traveling in the Arabian Sea, without sustaining any damage or injuries to the crew.[415] The Houthis stated that they had targeted it with their newly-acquired hypersonic missile called Hatem 2.[416]

Another missile later targeted the ship but landed in the nearby water. Both the ship and ita crew were reported to be unharmed following the attacks.[440]
Two ships were targeted in the Red Sea on 13 August. The first ship to be targeted was the Liberian-flagged oil tanker Delta Atlantica, which reported two explosions near it before being targeted by another explosion after a small watercraft flashed lights at it. The ship was attacked again a few hours later, being targeted by a USV which hit the ship but did not detonate, and was destroyed by its security guards.

The crew meanwhile however was reported to be safe[442] and was rescued on the following day by a French destroyer which was part of Operation Aspides.[289][288] The Houthis claimed the attack[443] and later attacked the ship again, publishing a video of the group purpotedly setting it on fire. The United States Department of Defense stated on 28 August that the ship was still on fire and had likely started leaking oil, while those attempting to salvage it were prevented from doing so due to the Houthis threatening to attack them as well.[444] The Operation Aspides mission however denied that there was any oil leakage.[445] The office of the Permanent Representative of Iran to the United Nations later stated that the group had agreed to let salvage crews rescue the tanker.[446] The Houthis on the following day published a video of them setting off bombs on the tanker.[447]
Five explosions were meanwhile also reported on 21 August near the Panama-flagged bulk carrier SW North Wind I, which was sailing near Aden. None of the blasts however affected the ship or its crew.

Issues
Disinformation
The Houthis and their supporters have engaged in a disinformation campaign to undermine efforts to secure freedom of navigation in the Red Sea and surrounding waters by the United States and its allies and to gain recognition as a regional power.[507] On 1 February 2024, the Houthis claimed an attack on a US ship named KOI, but maritime sources told BBC that it was false.[508] Hezbollah-affiliated news outlets such as Islam Times and Al Mayadeen have backed false claims by the Houthis. On 28 January, Islam Times released footage of the 2021 X-Press Pearl fire, purporting it displayed the aftermath of a Houthi attack on a British ship. Three days later, Al Mayadeen reported that the Houthis accurately struck USS Gravely, but the claim was rejected by US officials.[509]
Social media users on platforms such as X have published old or doctored images and videos falsely claiming them as Houthi attacks. In February 2024, users on X posted the 2018 sinking of the USS Racine (LST-1191) and the X-Press Pearl disaster, claiming they showed the Houthi attacks on the Star Nasia and Morning Tide.[510] In June 2024, users posted satellite images of the USS Dwight D. Eisenhower with damage digitally edited onto it, claiming that it was the result of a Houthi attack.[507] Other mislabeled or digitally edited photographs and videos were also published purporting damage to the aircraft carrier, though some were satire.[511][512]
Footage from the Czech-based video game Arma 3 has also been used to spread disinformation about the conflict, with Russian websites such as The Intel Drop and Pravda publishing gameplay, falsely claiming it showed attacks on the USS Dwight D. Eisenhower.
