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 missing crew.

Six mariners have been rescued after a deadly attack on a cargo ship that sank off rebel-held Yemen, an EU maritime force said Wednesday, as the search continued for the rest of the crew. Earlier, the British navy's United Kingdom Maritime Trade Operations had reported five crew had been rescued after "search and rescue operations commenced overnight".
