US Navy sinks 3 Houthi boats attacking merchant ship in Red Sea, US says

U.S. Navy helicopters returned fire and and sank three small boats carrying Houthi militants in the Red Sea on Sunday, after U.S. warships responded to a distress call from a merchant vessel, military officials said.

A Maersk container ship, the Singapore-flagged Hangzhou, issued a distress call at about 6:30 a.m. local time, U.S. Central Command said in a statement on Sunday. The merchant vessel said four small boats were attacking it.

"The small boats, originating from Houthi-controlled areas in Yemen, fired crew-served and small-arms weapons at the Maersk Hangzhou, getting to within 20 meters of the vessel, and attempted to board the vessel," Central Command said.

Helicopters from two U.S. ships -- the USS Eisenhower and the USS Gravely -- responded and issued verbal calls to the small boats, U.S. officials said.
