CAIRO (Reuters) - Yemen's Houthis said on Sunday that they had attacked two civilian ships along with an American destroyer in the Red Sea and Arabian Sea, their latest effort to disrupt shipping in what they say is support for Palestinians in Gaza.

In a statement, the Houthi military spokesperson, Yahya Saree, said the militant group fired ballistic missiles at the American destroyer, naval missiles at a ship called the Captain Paris, and drones at a ship called the Happy Condor. It was not clear whether any of the targets were hit.

Early on Sunday the United Kingdom Maritime Trade Operations (UKMTO) said that a vessel 40 nautical miles south of Yemen's al Mukha had reported two explosions nearby. The vessel and its crew were safe and continuing their journey, it said, without identifying the ship.

The Iran-aligned Houthis, who control Yemen's capital and most of it populated areas, have launched dozens of attacks on international shipping in the Red Sea region since November in solidarity with Palestinians.

The attacks have upended global trade by forcing ship owners to reroute vessels away from the Suez Canal, and drawn retaliatory U.S. and British strikes since February.
