The search for those missing after Yemen’s Houthi rebels sank a ship in the Red Sea has ended as at least four people are presumed dead and 11 others remain unaccounted for.

The incident occurred a day after Houthi militants in Yemen targeted another vessel, their first assault on shipping since President Trump announced a truce with them.

Yemen's Houthi rebels killed 3 mariners with an attack on a ship in the Red Sea, a European naval force says, fueling concern over a possible new wave of attacks by the Iran-backed group.
