Houthis claim to shoot down U.S. drone after weekend of self-defense strikes by U.S.

Yemen's Iranian-backed Houthi rebels say they shot down a U.S. drone and severely damaged a British-owned cargo ship in a missile attack early Monday morning.

This comes after a series of self-defense strikes by the U.S. military over the weekend on Houthi targets.
