The Department of State advises Americans worldwide to exercise increased caution.
Location: Worldwide @@@
Event: Due to heightened tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation.
Americans currently in the Middle East should exercise caution and heightened vigilance and should be prepared for flight cancellations, periodic airspace closures, and potential travel disruptions. Some airlines in the region have postponed resumption of earlier flight schedules; others have cancelled some routes.
Americans outside the Middle East should reconsider travel to and through the region. Those who do travel to or from the region should monitor information about airport and airline operations.
U.S. diplomatic facilities, including outside the Middle East, have been targeted. Iran and groups supportive of Iran may target other U.S. interests overseas or at locations associated with the United States and Americans throughout the world, including U.S. businesses and other institutions.
