The Federal ​Aviation Administration has warned flight operators of potential safety risks when flying to or over Saudi Arabia following the attacks.

The United States, the United Kingdom, and Canada issued alerts on Oct. 11 urging their citizens to avoid King Khalid International Airport in Saudi Arabia after a Houthi attack killed 13 people.

More than 300 were also injured after Yemen’s Iran-backed Houthis targeted a passenger terminal at King Khalid International Airport in Riyadh on Oct. 10. The terrorist group launched another attack at the airport on Oct. 11, leaving at least one person dead and 11 others injured.

The Federal ​Aviation Administration (FAA) on Oct. 11 warned flight operators of potential safety risks when flying to or over Saudi Arabia, citing ongoing military activity and navigation system interference.

“Threats could pose a potential risk to ​aircraft at all altitudes, including overflight, the arrival, and departure phases of flight,” the FAA said, warning of the potentially hazardous situation in Saudi Arabia.

The U.S. Embassy in Riyadh also issued an alert advising American citizens to stay away from King Khalid International Airport and to use extreme caution at other major airports in Saudi Arabia.

It advised citizens to stay alert for possible flight cancellations, airspace closures, and travel disruptions resulting from the airport attacks.

“If an aerial attack occurs, stay away from glass doors, windows, and any fallen debris, and monitor your phone and news outlets for official guidance,” the embassy stated.

According to the alert, U.S. government employees in Saudi Arabia must now obtain special authorization to use King Khalid International Airport or the airports in Jeddah and Dammam. They are also prohibited from traveling within 20 miles of the Yemen border due to safety risks.

The embassy said special authorization is required to travel to the provinces of Jizan, Asir, and Najran, and to the cities of Qatif, Yanbu, and Taif.

The Saudi General Authority of Civil Aviation also reported an attack at the King Fahd International Airport in Dammam, nearly 250 miles northeast of Riyadh, on Oct. 11.

It remains unclear how many people were injured in the attack. The aviation authority said it was still assessing the damage and verifying the safety of the affected facilities.

The United Kingdom advised its citizens to avoid all airports in Saudi Arabia, except Medina International Airport. It also urged citizens to avoid nonessential travel to Jeddah and Dammam, citing safety risks.

“There is a heightened threat against airports, military bases, ports and energy infrastructure across Saudi Arabia, including Abha, Jizan, Najran, Riyadh, Jeddah and Yanbu, as well as shipping in the Red Sea. Further attacks against airports are very likely,” it stated.

Canada warned its citizens against using King Khalid International Airport, saying military activity in the area could disrupt airport operations.

Turkey, Egypt, Pakistan, and Saudi Arabia said they strongly condemned the Houthis’ hostile attacks on Riyadh, saying the attacks “constitute a blatant violation of international law.”

The nations, collectively known as the R4 Group, said in a joint statement that they support “all legitimate measures and steps” Saudi Arabia intends to take to protect its sovereignty in line with the Charter of the United Nations and international law.

“The Group holds the Houthi militia fully accountable for the results of these attacks and any repercussions that come with it that threaten regional and international peace and security, and demands the immediate and unconditional halt of these attacks,” they stated.

The Houthis have said the attacks on Saudi Arabia were a response to the country’s support for government forces in Yemen’s reignited civil war. Saudi Arabia has expressed support for an offensive by Yemen’s U.N.-recognized government aimed at reclaiming territory held by the Houthis.
