The search for those missing after Yemen’s Houthi rebels sank a ship in the Red Sea has ended as at least four people are presumed dead and 11 others remain unaccounted for.

Private security companies have concluded the search for 11 missing crew members following the sinking of the bulk carrier Eternity C in the Red Sea on July 7. The vessel was struck by Houthi fighters using small arms and explosive-laden drones during a prolonged assault, which left four individuals presumed dead.

Commercial ships are broadcasting messages about their nationality and even religion on their public tracking systems to avoid being targeted by Yemen's Houthis.
