A vessel navigating the Red Sea off Yemen’s coast has come under attack involving gunfire and rocket-propelled grenades, according to the UK maritime agency.

A U.S. airstrike on a vital oil port held by Yemen’s Houthi rebels has resulted in over 70 deaths, marking a significant escalation in President Donald Trump’s military campaign against the Iranian-backed group. The attack, announced by the rebels on Friday, also left many wounded and underscores the intensifying conflict in the region.
