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.

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.

The U.S. military attacked an oil port in western Yemen, killing dozens of people as the Trump administration continues to intensify its strikes against the Houthi rebels.
