The ship was carrying a Russian-produced refined oil product on behalf of commodities trader Trafigura.On Saturday, Trafigura stated that no injuries or casualties had been reported on the 250m-long ship.However, the company added that the crew is still working to contain the fire in one of the ship’s cargo tanks with the help of military vessels, emphasizing that the safety of the crew remains their top priority.Previous Houthi strikes, mostly targeting container ships or ships for dry bulk commodities, have caused minimal damage and any fires were swiftly put out. This attack will likely prompt more shipowners to avoid the southern Red Sea and Gulf of Aden.Arsenio Dominguez, secretary-general of the United Nations’ International Maritime Organization, condemn the attack on the Marlin Luanda tanker, which he said has put seafarers’ lives at risk and raises concerns about potential environmental damage.The missile that struck the tanker was the first to hit a commercial vessel since the US and UK launched a second set of strikes against the militants on Monday. The Houthis have disrupted global trade by targeting the critical route to and from the Suez Canal.On Friday, the Houthis launched an anti-ship ballistic missile at the USS Carney, a US navy vessel in the Gulf of Aden. US Central Command said the Carney had successfully shot the missile down.On Saturday, American forces took action against a Houthi anti-ship missile that was preparing to fire, according to US Central Command.Yahya Saree, the Houthis’ spokesman, claimed the group had targeted the Marlin Luanda, which it described as a “British oil ship”. While the vessel was operating on behalf of Singapore-based Trafigura, its registered owner is Oceonix Services, a company based in the City of London.Trafigura stated that the vessel was carrying “Russian origin” Naphtha, an oil product, which it said had been purchased below the price cap on the country’s oil set by international sanctions.The Houthis said they are acting in solidarity with Palestinians in Gaza after Israel declared war on Hamas, the militant group that attacked Israel on October 7.The Yemeni rebels originally claimed they were only targeting vessels linked to Israel, although many of those affected had no apparent link to the Jewish state.The Houthis have since expanded their target list to include ships linked to the US and UK. Many shipping industry executives had believed that vessels carrying cargo to or from Russia or China would be protected to some extent based on a Houthi promise not to attack Russian and Chinese ships.Arrivals of container ships in the area in recent weeks have decreased by 90 per cent compared to levels in early November, according to Clarksons, a shipping services group. RecommendedMost are instead taking a longer route round the Cape of Good Hope, which has significantly increased journey times and costs.On Wednesday, the Houthis fired at least three missiles towards two US-flagged container ships, the Maersk Detroit and Maersk Chesapeake, as they were heading through the Bab-el-Mandeb, at the mouth of the Red Sea. The ships, part of a fleet of 20 US-flagged vessels carrying almost exclusively US government cargo, were accompanied by the USS Gravely. The US naval ship shot down two of the missiles, while another fell into the sea.Maersk, the world’s second-largest container shipping line, said it would no longer send its US-flagged fleet through the area. The Copenhagen-based company’s other vessels have been travelling via the Cape of Good Hope since December.
