Air operations were reported suspended at King Khalid International Airport in Riyadh on September 30, according to an unverified social media post. Saudi authorities have not confirmed the report.

It would be the second halt at the Saudi capital's main airport this month. Operations were suspended for about two hours on September 19 after the Houthi group fired a ballistic missile at Riyadh, according to Flightradar24 data, with 9 flights cancelled and 279 delayed.

The Saudi-led coalition said air defences intercepted the missile. Its spokesman, Major-General Turki al-Maliki, said the Houthis tried to target civilian infrastructure in Bisha, Taif, Farasan and Yanbu. Houthi military spokesman Yahya Saree said the group attacked "sensitive" sites in Riyadh. Saudi authorities reported no casualties or damage, though a plume of smoke was seen rising near the airport's fuel storage area.

The alert on September 19 was Riyadh's first since fighting in Yemen escalated in July. Saudi Arabia's cabinet on September 29 welcomed a UN Security Council statement condemning continued Houthi attacks on the kingdom and on commercial vessels.

Airlines have kept Riyadh services curtailed. Air France and KLM have suspended flights to the Saudi capital until October 24, while British Airways is due to resume a reduced service on November 3.

King Khalid International Airport opened in 1983 and is the main international gateway to the Saudi capital. It is operated by Riyadh Airports.
