The State Department on Sunday night issued a global travel advisory warning Americans abroad to exercise increased caution after the United States attacked Iran's nuclear facilities the night prior.

The US State Department issued a “Worldwide Caution” alert for American citizens, flagging the potential of travel disruptions and demonstrations following the US strikes on Iranian nuclear facilities.
