Residents of Saudi Arabia’s capital Riyadh witnessed smoke and flames rising from an area near the international airport on Saturday, news agencies AFP and Reuters reported.
The development came after Saudi Arabia warned of a “hostile aerial threat” and issued emergency alerts across the country, including Riyadh, late Friday and early Saturday. Flight-tracking data also showed “major problems” with aircraft arrivals and delays at the airport.

ABP has not independently verified the videos. The Saudi government did not immediately respond to the development.
Saudi civil defence had sent phone alerts overnight warning of potential danger in Riyadh and the city of Al-Kharj, east of the capital. An all-clear was subsequently issued on Saturday morning.
Reuters reported that a journalist heard booms before the all-clear was issued.
Escalation With Iran-Backed Houthis
Hostilities between Saudi Arabia and the Iran-backed Houthis in Yemen escalated in July, when the Houthis declared a naval blockade against Riyadh and began launching attacks.
The Houthis, who control the most populous parts of Yemen and much of the north, targeted Saudi vessels in the Red Sea.
The attacks signal new threats to the global oil supply, putting at risk the main alternative Red Sea route for Gulf exports, while traffic through the Strait of Hormuz remains affected, Reuters reported.
