Black smoke visible near Riyadh airport: Reports

RIYADH: A large plume of smoke was visible near Riyadh's main airport on Saturday after booms were heard and Saudi Arabia sent alerts overnight warning of potential danger around the capital, amid an escalation in attacks by Yemen's Ansar Allah group.

Aircraft tracking website FlightRadar24 reported major issues at the Saudi capital's Riyadh King Khalid International Airport, including cancellations and delays.

The airport was listed under the site's maximum disruption index of 5.0, meaning the airport was seeing 'major problems with long delays and several cancelled flights'.
Reuters video ⁠and photographs showed a huge pillar of black smoke rising in the area, with ⁠the airport highway, main terminal building and other facilities in the foreground.
There was no immediate comment from the Saudi government's media office in response to Reuters questions about the smoke and the overnight alerts.
Saudi civil ‌defence sent the alerts by phone overnight for potential ​danger in Riyadh and ⁠the city of Al-Kharj east of the capital, before issuing an ​all-clear on Saturday morning. A Reuters journalist ‌in Riyadh's Olaya area heard booms before the all-clear was sent.
Although some alerts had been issued in Riyadh this year after the ​start of the US-Iran war, these were the first since the escalation began with the Ansar Allah in July.
The Ansar Allah, who control the most populous parts of Yemen and much of the north, have been launching attacks towards Saudi Arabia since declaring a naval blockade against Riyadh in July, with strikes ‌targeting Saudi vessels in the Red Sea.
The attacks have created new threats to ​global oil supplies, putting at risk the main alternative Red Sea route for Gulf exports while ​traffic ‌through ⁠the Strait of Hormuz remains blockaded.
On Friday Ansar Allah military spokesperson Yahya Saree said the group had foiled unspecified 'criminal attempts' in the Yemeni capital Sanaa, blaming Saudi Arabia and vowing a response.
The Iran-aligned ​group, which seized Yemen's entire Red Sea coast in a lightning ⁠advance this ​month, says the Saudi Air Force has conducted hundreds of airstrikes against it in recent days.
The UN Security Council in a statement on Friday 'condemned in the strongest terms continued Houthi attacks against the Kingdom of Saudi Arabia, including attacks impacting civilian and energy infrastructure, which have resulted ​in the injury of civilians, including women and children.'
