The U.S. State Department issued a global travel warning Sunday after American forces struck three nuclear sites in Iran.
The alert advises Americans to be cautious while traveling abroad. It warns of possible protests or violence targeting U.S. citizens, particularly in the Middle East, where air travel has already been disrupted by the conflict between Israel and Iran.
“The conflict between Israel and Iran has resulted in disruptions to travel and periodic closure of airspace across the Middle East,” the advisory said. “There is potential for demonstrations against U.S. citizens and interests abroad.”

On Saturday, President Donald Trump ordered the U.S. to join Israel’s offensive against Iran, authorizing strikes on three Iranian nuclear sites: Fordow, Natanz, and Isfahan. In response, Iranian officials warned they would retaliate against the United States.
According to flight tracking data, commercial planes are avoiding Iranian, Iraqi, Syrian, and Israeli airspace. Flights to Dubai, Doha, and Riyadh have been canceled in recent days.
As everyone expected airspace around UAE, predominantly Dubai and Abu Dhabi fully closed now to international carriers, huge amount of turn around ongoing in the area.

The Department of Homeland Security also issued an alert on Sunday warning of heightened threats within the U.S., including potential cyberattacks by pro-Iranian groups and the risk of violence if religious leaders call for retaliation.
Travelers are encouraged to register with the State Department’s Smart Traveler Enrollment Program to receive updates and emergency notifications. The agency also advises staying vigilant, avoiding large gatherings, and preparing a backup plan in case of disruptions.
