Missiles fired by Yemen's Houthi militants struck the Palau-flagged Verbena cargo ship in the Gulf of Aden on Thursday, sparking a fire and severely injuring one of her crew, U.S. Central Command said, Paralel.Az reports citing Reuters.

The Iran-allied Houthis have attacked international shipping in the Red Sea region since November in solidarity with the Palestinians in the war between Israel and Hamas.

Thursday's attack marked their second direct hit on a merchant ship in two days, and the group said its campaign would continue until hostilities in the Gaza Strip end.

Three missiles struck the Verbena on Thursday, sparking a fire and damaging the ship, the United Kingdom Maritime Trade Operations (UKMTO) agency said.

While her crew fought the fire, an aircraft from the U.S. Navy's Philippine Sea warship medically evacuated the injured mariner to a partner force ship nearby for medical attention, U.S. Central Command said.

Reuters was not immediately able to contact the Verbena's Polish manager. The vessel, loaded with wood construction material, was sailing to Italy at the time of the attack, CENTCOM said. Security and military sources said the Verbena still has power and steering capabilities.
