Rescuers launched a search Wednesday for survivors of a Liberian-flagged cargo ship that came under attack from Yemen's Houthi rebels in the Red Sea, authorities said. At least three mariners were killed and two were wounded.

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.

Yemen’s Houthi militants sank two commercial ships and killed sailors during three days of attacks in the Red Sea this week — a stark reminder to vessel owners and crews of the risks of traversing the maritime chokepoint.
