The US State Department issued an alert urging American citizens around the world to “exercise increased caution” over the war with Iran.

Axar.az reports the department said that 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," the alert noted.

"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," the alert added.
