Houthi rebels in Yemen have launched a violent new wave of attacks on ships in the Red Sea, sinking two vessels and killing crew members.

Yemen's Houthi rebels killed 3 mariners with an attack on a ship in the Red Sea, a European naval force says, fueling concern over a possible new wave of attacks by the Iran-backed group.

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.
