DUBAI, United Arab Emirates (AFP) — A merchant ship is thought to have sunk in the Red Sea after a deadly attack by Yemeni rebels that forced it to be abandoned last week, a security agency said.

The MV Tutor, which was holed during an attack that left one Filipino sailor dead, is “believed to have sunk,” the United Kingdom Maritime Trade Operations (UKMTO) said late Tuesday.

“Military authorities report maritime debris and oil sighted in the last reported location,” said UKMTO, which is run by the British navy.

The Liberian-flagged, Greek-owned and -operated bulk carrier was hit by a remote-controlled sea drone and an aerial projectile southwest of rebel-held Hodeida on 12 June.

It was evacuated in a military operation on Friday and left drifting, its engine room breached and taking on water.

The Iran-backed Houthi rebels have launched scores of drone and missile attacks on the vital sea route since November, describing them as retaliation for the Israel-Hamas war.

The White House announced the sailor’s death on Monday. National Security Council spokesperson John Kirby said a Sri Lankan crew member was critically wounded in a separate Houthi attack on the MV Verbena on Thursday.

The Tutor appears to be the second ship sunk by the Houthis in recent months after the Rubymar, carrying thousands of tons of fertilizer, went down in the Red Sea in March after a missile strike.

The Houthis, who seized Yemen’s capital Sanaa in 2014, have been at war with a Saudi-led coalition since 2015.

The United Nations says the conflict has left hundreds of thousands of people dead, through fighting or indirect causes like lack of food, and created one of the world’s worst humanitarian crises.
