A U.S. warship shot down 14 suspected attack drones over the Red Sea on Saturday, and a Royal Navy destroyer downed another drone that was targeting commercial ships, the British and American militaries said.

Houthi rebels in Yemen have launched a series of attacks on vessels in the Red Sea, one of the world’s busiest shipping routes, and have launched drones and missiles targeting Israel, as the Israel-Hamas war threatens to spread.

U.S. Central Command said that the destroyer USS Carney “successfully engaged 14 unmanned aerial systems” launched from Houthi-controlled areas of Yemen.
