The US says the attack on the Red Sea coast aimed to restrict supplies and funds for the Houthis, who called it a war crime.

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. 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.
