The United States carried out a strike on a Houthi radar site in Yemen early Saturday local time, U.S. Central Command said. It follows a remarkable escalation in the Middle East this week, when a U.S.- and U.K.-led coalition attacked Houthi militants in Yemen, striking dozens of targets and using more than 150 munitions. The Iran-backed Houthis have drawn international condemnation for targeting commercial shipping vessels in the Red Sea to protest Israel’s military campaign in Gaza, and the group vowed Friday that the attacks would continue.
