Americans abroad should follow the guidance in security alerts issued by the nearest U.S. embassy or consulate. Flight cancellations and periodic airspace closures may cause travel disruptions.

Groups supportive of Iran may target other U.S. interests overseas or locations associated with the United States and/or Americans throughout the world.
