The U.S. State Department has issued a "Worldwide Caution" security alert, warning American citizens of the increased risk of terrorism and violence against U.S. interests abroad following escalating global tensions, including the recent conflict involving Iran.

In a statement released Sunday, the department advised all U.S. nationals traveling or residing overseas to remain vigilant, avoid large public gatherings, and closely monitor local media and embassy communications.

“Due to heightened tensions in various regions, there is a continued risk of terrorist attacks, demonstrations, or violent actions against U.S. citizens and interests,” the alert read.

The warning comes days after U.S. airstrikes targeted Iranian nuclear facilities, sparking condemnation from several international actors, including China and Russia. Intelligence agencies have since indicated increased chatter from hostile groups threatening retaliation.

Embassies worldwide have reportedly tightened security protocols, while some U.S. consulates have temporarily suspended non-essential services in select high-risk regions.

The State Department emphasized the importance of enrolling in the Smart Traveler Enrollment Program (STEP) to receive real-time safety updates and help embassies reach citizens in emergencies.

This is the first Worldwide Caution alert issued in 2025 and reflects growing concerns about instability in the Middle East, cyber threats, and coordinated attacks on Western assets.
