The Houthis claimed responsibility for the assault that maritime officials say killed four of the 25 people aboard the Eternity C before the rest abandoned the cargo ship.

Rescuers found four more crew members Thursday who went missing after Yemen's Houthi rebels sank a ship in the Red Sea as the United States alleged the group may “have kidnapped” others on board.

Rescuers launched a search Wednesday for survivors of a Liberian-flagged cargo ship that came under attack from Yemen's Houthi rebels in the Red Sea, authorities said.
