The US Mission in Saudi Arabia issued a nationwide security alert on Saturday, urging Americans to exercise “heightened vigilance” amid an increased threat of Houthi attacks, Anadolu Agency reported.
The mission said Houthi attacks on civilian airports and other critical infrastructure in Saudi Arabia had caused civilian casualties and severe travel disruptions. It warned that hostilities could spread “rapidly.”
“Please take extreme caution if you choose to use airports in Saudi Arabia,” the mission said, advising travelers to confirm their flight status directly with both their airline and the airport.
Riyadh’s King Khalid International Airport partially reopened on Oct. 23 for domestic flights and some international services operated by Saudi carriers, according to the mission. A limited number of flights normally based in Riyadh were operating from Prince Naif bin Abdulaziz International Airport in Qassim. Airports in Jeddah and Dammam remained open, although some delays and cancellations were reported.
The State Department ordered non-emergency US government employees and family members of US government staff to leave Saudi Arabia on Oct. 23. US government employees working in the kingdom require special authorization from the chief of mission to use any Saudi airport and are barred from traveling within 20 miles of the Yemeni border.
All land border crossings, including the King Fahd Causeway to Bahrain, remained open, the mission said. It also urged Americans to follow emergency alerts issued by Saudi Civil Defense.
The alert comes amid escalating tensions between the Houthis and Saudi Arabia. The coalition has reported repeated interceptions of missiles and drones targeting the kingdom.
Yemen has been mired in conflict since the Houthis seized Sanaa and other provinces in 2014, prompting a Saudi-led coalition to intervene in support of the government in 2015.
