The US has ordered the departure of diplomatic personnel and adjusted staffing at embassies across the Middle East as a result of Iranian efforts to target Americans, as well as threats from Houthi militants in Yemen, according to an American official. The State Department had previously said the US was ordering some diplomatic staff to depart only from Saudi Arabia as a result of the growing risk from the Houthis, but had called reports of broader US evacuations across the Middle East “inaccurate.”
