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.

The attack on the Eternity C, which killed at least three of the crew, represents the most serious assault carried out by the Houthis in the crucial maritime trade route.

Video released by the Houthi media center shows the bulk carrier ‘Magic Seas’ being attacked and later sinking in the Iran-backed rebel group’s first attack this year on a commercial shipping vessel in the Red Sea.
