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.

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.

An intense series of suspected U.S. airstrikes hit sites across Yemen held by the Houthi rebels, with at least one person reportedly being killed in the capital, Sanaa.
