The U.S. Department of State issued a worldwide caution advisory, urging Americans traveling abroad to exercise increased vigilance amid rising geopolitical tensions.

In a security alert published March 22, the agency warned that U.S. diplomatic facilities and American interests overseas could be potential targets, particularly by groups supportive of Iran.

The advisory applies globally but emphasizes heightened caution in the Middle East. The State Department also warned travelers to prepare for potential disruptions, including periodic airspace closures that could affect international flights. Americans overseas are encouraged to monitor guidance issued by their nearest U.S. embassy or consulate and review destination-specific travel advisories before departure.
