An advisory from the US Mission to Saudi Arabia has put American travellers on notice about possible airport attacks, airspace restrictions, and disruptions to flights in the country, citing a series of recent drone and missile strikes on Saudi airports.

A notice distributed by the mission on October 16 conveyed that Saudi Arabia's General Authority of Civil Aviation had extended the halt on flights at King Khalid International Airport in Riyadh to run until October 17. Both King Abdulaziz International Airport in Jeddah and King Fahd International Airport in Dammam are continuing to handle flights, though a number of services have faced delays or been cancelled.

Travellers holding US citizenship were advised by the mission to take precautions at Saudi Arabian airports and to verify flight information directly through their carriers and the relevant airport authorities. Residents were urged by the US Mission to monitor security notices pushed to mobile devices by Saudi Arabia's Civil Defence.

Alongside rail services, road coaches, and privately driven vehicles, the notice drew attention to other ways passengers could reach or depart the Kingdom. Passengers looking to book journeys were directed to check timetables and seat availability by contacting transport operators directly — among them Saudi Arabia Railways, SAT Transportation, and SAPTCO.

Airports serving Bahrain, Jordan, Oman, Qatar, and the UAE — all countries bordering the affected area — were reported to be functioning without interruption, according to the mission. Those heading to the airport were urged to check on terminal and flight operations before setting out.

Under the advisory, American nationals were informed that Saudi Arabia's Interior Ministry bars the recording, distribution, or online posting of any material related to missile and drone intercepts or the locations where strikes land. Penalties for non-compliance, the ministry's notice stated, could expose parties to legal responsibility under applicable law.

According to a statement from the US Mission, a number of American nationals were taken into custody after breaching local restrictions — among the violations cited were photographing government buildings, airports, and locations affected by strikes. Anyone travelling through or living in Saudi Arabia is expected to follow the country's applicable legal framework.

The advisory issued by the mission urged Americans in Saudi Arabia to monitor local news outlets and follow directives from Saudi authorities, position themselves away from windows, glass doors, and any fallen debris if an aerial attack were to occur, keep mobile devices charged and track official notifications, avoid demonstrations, large gatherings, and areas with a visible police presence, stay alert at locations publicly associated with the United States, and contact airlines directly about any changes or cancellations to flights.

Those posted to government roles within Saudi Arabia are required to obtain advance clearance from the Chief of Mission before travelling through any airport in the country. A travel restriction within 20 miles of the Yemen border applies to them, and entry into a number of areas — among them Jizan, Asir, Najran, Qatif, Yanbu, and Taif — requires prior official clearance.

Both routine and urgent consular assistance for US citizens remained accessible through the mission. Four distinct contact numbers serve emergency purposes across the country: the consolidated response line sits at 911, with dedicated lines for police at 999, ambulance services at 997, and highway security at 996.

Through the State Department's Smart Traveler Enrollment Program (STEP), American nationals abroad can register to receive security-related updates and make it easier for the nearest US Embassy to reach them when emergencies arise.
