US airstrikes on an oil port in western Yemen have killed at least 38 people, Houthi-run Al-Masirah TV reported Friday, marking one of the deadliest days since the United States escalated its aerial military campaign against the Iranian-backed group in recent weeks.

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.

U.S. airstrikes targeting an oil port held by Yemen’s Houthi rebels killed 74 people and wounded 171 others, the group said Friday, in the deadliest known attack under President Donald Trump’s new military campaign against the Iranian-backed faction.
