WASHINGTON D.C (VINnews)-The United States urged American citizens to leave Iran immediately, warning of widespread internet shutdowns, transportation disruptions and heightened security measures across the country.

In a security alert, U.S. officials said Iranian authorities continue to impose restrictions on mobile, landline and national internet networks, limiting communications nationwide. Airlines have also reduced or canceled flights to and from Iran, raising concerns that Americans could face difficulty departing on short notice.

The advisory said U.S. citizens should expect continued internet outages and prepare alternative means of communication. If it is safe to do so, Americans were advised to consider leaving Iran by land through Armenia or Türkiye.

“Leave Iran now,” the alert stated, adding that travelers should not rely on U.S. government assistance to depart the country.

Those unable to leave were urged to find secure shelter, maintain adequate supplies of food, water and medications, and avoid public demonstrations. U.S. officials also advised Americans to keep a low profile, monitor local media for breaking developments, and be prepared to change plans quickly.

The State Department noted that flight cancellations and disruptions could occur with little or no warning and encouraged travelers to check directly with airlines for updates.

Americans in Iran were further urged to keep phones charged, maintain contact with family and friends, and enroll in the Smart Traveler Enrollment Program (STEP) to receive security updates.

The alert comes amid ongoing instability and heightened tensions in the region, prompting increased security measures by Iranian authorities and renewed warnings from the U.S. government about the risks of remaining in the country.
