Four people are presumed dead and 11 others are still missing after a Liberian-flagged cargo ship sank in the Red Sea following an attack by Yemen's Houthi rebels, a European Union naval mission said Friday.

A total of 10 crew members have been rescued so far after Yemeni militants sank a Greek-owned cargo ship in the Red Sea.

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.
