Worldwide Caution: The Department of State advises Americans worldwide to exercise increased caution. 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 possible flight cancellations, periodic airspace closures, and potential travel disruptions.  Please monitor embassy and consular security alerts, local authorities, and the news for breaking developments.  Americans outside the Middle East should reconsider travel to and through the region. 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.  Enroll at step.state.gov to receive the latest security alerts and follow the “U.S. Department of State – Security Updates for U.S. Citizens” channel on  WhatsApp or @TravelGov on X.  When planning travel, carefully read the Travel Advisory and detailed information for your destination, and any recent alerts at  travel.state.gov/destination.
