U.S. diplomatic missions in Israel and the Middle East have renewed their blanket security warning to American citizens in the region, amid heightened security tensions and fears of rapid escalation. The warning stated that Iran and its proxy organizations – including the Houthis who have attacked targets in Saudi Arabia – may target American diplomatic missions, businesses and institutions in the Middle East and worldwide. Citizens were warned of potential flight disruptions and airspace closures in the region, and urged to maintain heightened vigilance, stock up on food and water and download real-time alert applications.
