At least three of the 25 people on board the Eternity C were killed after it was attacked by the Iran-backed group.

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.

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.
