Middle East: Due to tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation. Americans currently in the Middle East should exercise heightened vigilance and be aware of potential flight cancellations, airspace closures, and travel disruptions. Iranian-supported Houthis have engaged in hostilities against Saudi Arabia, including civilian airports. This military conflict has the potential to escalate rapidly. Americans outside the Middle East should seriously 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.
