The U.S. Department of State is urging Americans worldwide, particularly those in the Middle East, to exercise more caution amid the ongoing conflict with Iran.
In a “Worldwide Caution” notice on Feb. 28, the department told U.S. citizens abroad to follow the most recent security alerts issued by the nearest U.S. embassy or consulate. The alert warned that Americans “may experience travel disruptions due to periodic airspace closures” and advised heightened vigilance, especially in the Middle East.
