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.

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.
