- The State Department warned on September 19, 2026, that Iran and supporters may target Americans and U.S. interests overseas.
- Officials placed Iran, Iraq, Lebanon, Syria, Gaza and Yemen under Level 4: Do Not Travel advisories.
- Saudi Arabia added travel limits near Yemen, including 20 miles of the border and special approval for several cities.
The U.S. Department of State issued a security alert on September 19, 2026, warning that Iran and groups supporting it may target Americans and U.S. interests overseas as tensions rise across the Middle East.
The warning extends beyond the region. U.S. diplomatic facilities, including facilities outside the Middle East, have been targeted, and the alert says U.S. businesses and other institutions could also face attacks at locations associated with the United States and Americans.

Americans already in the region should exercise heightened vigilance. They should also prepare for flight cancellations, airspace closures and other travel disruptions.
People outside the region should seriously reconsider travel to and through it. Conditions could change quickly.
The department described the security environment as complex and warned of a possible escalation that officials could not foresee. It also said the military conflict could escalate rapidly.
“Due to tensions in the Middle East, the security environment remains complex with the potential for unforeseen escalation.”
The alert specifically cited Iranian-supported Houthis and their hostilities against Saudi Arabia, including civilian airports. Travelers who continue to fly should check airport and airline operations directly before departure and during their journey.
Travel advisories divide the region between Level 3 and Level 4 warnings
The U.S. government’s country guidance assigns the highest warning level to six locations. Iran, Iraq, Lebanon, Syria, Gaza and Yemen remain at Level 4: Do Not Travel.
Eight other locations carry Level 3: Reconsider Travel advisories. They are Saudi Arabia, Israel, Jordan, Kuwait, Oman, Qatar, Bahrain and the United Arab Emirates.
| Advisory level | Locations | Guidance |
|---|---|---|
| Level 4 | Iran, Iraq, Lebanon, Syria, Gaza and Yemen | Do Not Travel |
| Level 3 | Saudi Arabia, Israel, Jordan, Kuwait, Oman, Qatar, Bahrain and the United Arab Emirates | Reconsider Travel |
The alert circulated through diplomatic channels covering Iran, Israel, the West Bank, Gaza, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, the United Arab Emirates, Iraq, Bahrain and Syria. The notices remained active on September 20, 2026.
Saudi Arabia has added restrictions near Yemen and several other areas
Saudi Arabia remains under a Level 3 advisory. Separate rules limit travel by U.S. government employees in parts of the country.
Those employees may not travel within 20 miles of the Yemen border. Trips to Jizan, Asir, Najran and Qatif require special authorization.
The restrictions sit alongside the warning about attacks involving civilian airports. Travelers headed to or from Saudi Arabia should check whether airlines and airports are operating before leaving for the terminal.
The notice does not limit the risk to military sites. It identifies airports, U.S. businesses and other institutions associated with Americans as possible targets.
Travelers are told to watch operations and follow local instructions
The department’s guidance calls for several steps:
- Check airline and airport status directly, rather than relying only on an earlier itinerary.
- Keep phones charged in case schedules, routes or local instructions change.
- Follow directions from local authorities.
- Avoid demonstrations and large gatherings.
- Enroll in the Smart Traveler Enrollment Program (STEP).
The operational warning applies to both ends of a trip. A traveler may face a cancellation, an airspace closure or a disruption after departure, even if the original flight operated normally.
The alert also warns that Iran and groups supporting it may target other U.S. interests overseas. That language includes locations outside the immediate conflict zone.
Americans in Iran face the strongest instruction in the notice:
“Do not travel to Iran for any reason. U.S. citizens should leave Iran now.”
The security alert remained active in embassy and mission notices on September 20, 2026. Travelers with plans involving the region should check current airport and airline operations before beginning the trip.
