Riyadh:The US State Department has mandated the evacuation of non-emergency government employees and their families from Saudi Arabia due to increasing attacks by Yemen's Houthi group, as confirmed by the US Embassy on Friday.

According to Anadolu Agency – English, the US Mission to Saudi Arabia issued a security alert stating that the departure order became effective on October 23, prompted by safety risks.

The mission highlighted that Houthi assaults on civilian airports and critical infrastructure have resulted in casualties and significant travel disruptions, warning that the hostilities could intensify swiftly. US government personnel are now required to obtain special authorization to use Saudi airports after recent missile and drone attacks.

The embassy noted that Riyadh's King Khalid International Airport has partially reopened, while airports in Jeddah and Dammam continue to operate with some delays and cancellations. American citizens have been advised to exercise extreme caution when flying and are warned against photographing missile interceptions or attack sites, as per Saudi regulations.

This alert coincides with increased Houthi attacks on Saudi Arabia. On Thursday, the Saudi-led coalition announced that its air defenses intercepted and destroyed two ballistic missiles launched by the Houthis toward Riyadh. On Friday, the coalition reported intercepting a Houthi cruise missile aimed at western Saudi Arabia, along with a drone in the Riyadh region.

The Houthis have also claimed responsibility for attacks on Saudi oil facilities and airports in recent days. The Saudi-led coalition intervened in Yemen in March 2015 to support the internationally recognized government against the Houthis, who have held control of the capital Sanaa since September 2014.
