The Iran-backed Houthis said they attacked the Eternity C because it was heading to Israel, and that they took an unspecified number of crew to a "safe location".

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.
