The death toll from US airstrikes on an oil port in western Yemen has risen to at least 74 people, the Houthi-run health ministry reported, marking the deadliest day since the United States escalated its aerial campaign against the Iran-backed group last month.

More than 70 people were killed in a US airstrike on an oil port in Yemen held by Houthi rebels. The strike was in response to Houthi attacks on the Red Sea and Israel.

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