Yemen's Houthi rebels say the U.S. military has launched a series of airstrikes on the capital, Sanaa, and a rebel-held coastal city.

U.S. airstrikes targeting an oil port held by Yemen's Houthi rebels killed dozens and wounded more than 100 others, the group says.

U.S. strikes on Yemen's Ras Isa fuel terminal on the Red Sea coast have killed at least 74 people in the deadliest attack since the U.S. started its bombing campaign against the Houthis last year, according to the Houthi-run health ministry.
