Fires broke out on a Greek-flagged oil tanker previously attacked by Yemen’s Houthi rebels this week, with the vessel now appearing to be adrift in the Red Sea, authorities said.
It was not immediately clear what had happened to the oil tanker Sounion, which had been abandoned by its crew on Thursday and reportedly anchored in place.
The Houthis did not immediately acknowledge the fire.
The rebels are suspected to have gone back and attacked at least one other vessel that later sank as part of their months-long campaign against shipping in the Red Sea over the ongoing Israel-Hamas war in the Gaza Strip that has disrupted a trade route that typically sees one trillion dollars in goods pass through it annually.
The British military’s United Kingdom Maritime Trade Operations centre reported the fires in a note to mariners on Friday night.
“UKMTO have received a report that three fires have been observed on vessel,” the centre said. “The vessel appears to be drifting.”
A US defence official, speaking on condition of anonymity to discuss intelligence matters, said American officials were aware of the fires and continued to monitor the situation.
The vessel had been staffed by a crew of 25 Filipinos and Russians, as well as four private security personnel, who were taken by a French destroyer to nearby Djibouti, the EU’s Aspides naval mission in the Red Sea said on Thursday.
The Sounion has 150,000 tons of crude oil aboard and represents a “navigational and environmental hazard,” the mission warned.
“It is essential that everyone in the area exercises caution and refrains from any actions that could lead to a deterioration of the current situation.”
The Houthis have targeted more than 80 vessels with missiles and drones since the war in Gaza started in October.
They seized one vessel and sank two in the campaign that also killed four sailors.
Other missiles and drones have either been intercepted by a US-led coalition in the Red Sea or failed to reach their targets.
The rebels maintain that they target ships linked to Israel, the US or the UK to force an end to Israel’s campaign against Hamas in Gaza.
However, many of the ships attacked have little or no connection to the conflict, including some bound for Iran.
As Iran threatens to retaliate against Israel over the assassination of Hamas leader Ismail Haniyeh in Tehran, the US military told the USS Abraham Lincoln aircraft carrier strike group to sail more quickly to the area.
Early on Thursday, the US military’s Central Command said that the Lincoln had reached the waters of the Middle East, without elaborating.
Washington also has ordered the USS Georgia-guided missile submarine to the region, while the USS Theodore Roosevelt aircraft carrier strike group was in the Gulf of Oman.
Additional F-22 fighter jets have flown into the region and the USS Wasp, a large amphibious assault ship carrying F-35 fighter jets, is in the Mediterranean Sea.
