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 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.

The incident occurred a day after Houthi militants in Yemen targeted another vessel, their first assault on shipping since President Trump announced a truce with them.
