An Iran-backed militant group raided a U.S. diplomatic facility in Yemen, compounding the recent kidnapping of Yemeni staff who worked for the State Department.

“We call on the Houthis to immediately vacate it and return all seized property,” a State Department spokesman told the Washington Examiner. “The U.S. government will continue its diplomatic efforts to secure the release of our staff and the vacating of our compound, including through our international partners.”
