The Iran-aligned Huthis, who control Yemen’s most populous regions, said on Thursday that they had attacked the Sounion oil tanker as part of their 10-month campaign against commercial shipping to support Palestinians in the war between Israel and Hamas in Gaza.
The Huthis first damaged the tanker on Wednesday with repeated attacks that caused a fire and a loss of engine power. A European warship later rescued her crew of 25. The uncrewed vessel was anchored between Yemen and Eritrea, a maritime security source told Reuters on Thursday.
On Friday, UKMTO said in an advisory that it had received reports of three fires on the vessel, which “appears to be drifting.” Later in the day, the Huthis posted a video on social media that purportedly showed them setting the tanker on fire.
The damaged tanker, carrying 150,000 metric tons of crude oil, poses an environmental hazard, the EU’s Red Sea naval mission Aspides said.
“A potential spill could lead to disastrous consequences for the region’s marine environment,” the Djibouti Ports & Free Zones Authority said in a post on the social media site X on Friday.
The largest recorded ship-source spill was in 1979, when about 287,000 tonnes of oil escaped from the Atlantic Empress after it collided with another crude carrier in the Caribbean Sea off the coast of Tobago during a storm, according to International Tanker Owners Pollution Federation.
The Sounion was the third vessel operated by Athens-based Delta Tankers to come under Huthi attack this month.
The Huthis said it attacked the tanker in part because Delta Tankers violated its ban on “entry to the ports of occupied Palestine,” Huthi military spokesman Yahya Saree said in a televised speech.
“Delta Tankers is doing everything it can to move the vessel (and cargo). For security reasons, we are not in a position to comment further,” the company said in a statement on Friday.
