US Issues Worldwide Caution After Iran Strikes

The U.S. State Department issues a rare Worldwide Caution on February 28, 2026, urging Americans everywhere to heighten vigilance following U.S. combat operations against Iranian targets. Travelers face risks of retaliatory violence, sudden airspace closures, and flight disruptions, especially in the Middle East where embassies in Qatar, Jordan, Bahrain, UAE, and Israel issue shelter-in-place orders.
