A Liberian-flagged cargo ship came under fire on Monday in the Red Sea, with two security guards on board reportedly hurt and two others missing in an assault that came after Yemen's Houthi rebels purportedly sunk another vessel in a similar attack.

Two crew members of a Liberian-flagged cargo ship have been killed in an attack in the Red Sea off the coast of Yemen, Liberia says. A Liberian representative to the International Maritime Organization (IMO) said the Eternity C was "attacked horribly... causing the death of two seafarers".

Rescuers are searching for more than a dozen crew members missing after Yemen's Houthi rebels sank a ship in the Red Sea
