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 one of the deadliest days since the United States escalated its aerial military campaign against the Iranian-backed group in recent weeks.

President Trump has vowed the Iran-backed Houthi militia will be “completely annihilated.” But forceful American strikes do not seem to have deterred the Yemeni fighters.

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.
