Rescuers pulled three more crew members and a security guard alive from the Red Sea on Thursday, maritime security sources said, a day after Houthi militants sank the Greek ship Eternity C and said they were holding some of the crew still missing.

The Houthis released dramatic footage of the sinking of the Liberian-flagged, Greek-owned Eternity C, which the rebels targeted with gunfire and explosive drones for hours, killing at least three crew members.
