Smoke and Flames Visible Near Riyadh Airport Amid Major Flight Disruptions

A plume of black smoke and visible flames emerged near Riyadh's main international airport on Saturday, while residents reported hearing loud explosions and booms. The incident occurred hours after Saudi authorities issued the first emergency air raid alert for the country's capital since the latest escalation in hostilities involving Yemen's Iran-backed Houthi rebels.

According to an on-site journalist from Agence France-Presse, a fuel storage tank bearing the logo of Saudi oil giant Aramco caught fire near the airport facility. Firefighters could be seen working at the scene to extinguish the flames surrounding the damaged structure.

Flight tracking data from FlightRadar24 indicated significant operational challenges at King Khalid International Airport on Saturday. The aviation tracking site placed the airport under its maximum disruption index rating of 5.0, reflecting major problems characterized by long delays and numerous flight cancellations.

The visible fire and reported explosions followed overnight warnings sent by Saudi authorities to residents across several regions, alerting them to potential danger surrounding the capital. Hours after the initial early morning alert, residents noted hearing additional sounds resembling a further round of explosions echoing through various parts of Riyadh.

Local residents described the unfolding situation with deep concern. One central Riyadh resident told AFP that the incident was terrifying, noting anxiety was heightened because the typical "all-clear" signal did not arrive immediately after the alarm. Another resident living in the city's northern sector reported that windows shook during the event, calling it unexpected and frightening.

Saudi authorities have not officially commented on the specific threat mentioned in the overnight warnings sent to residents, nor have they identified the precise origin of the attack. The security incident follows recent accusations from Riyadh earlier in the week alleging that the Houthis targeted Mecca, a claim that the group strongly denied.

The broader regional escalation comes as Yemen's Houthis carry out a swift military offensive this month, seizing swathes of territory and taking control of the country's Red Sea coast, including the vital Bab al-Mandab strait. In response, Saudi Arabia has conducted numerous air strikes on Houthi-held areas while struggling to halt their territorial advances.

Diplomatic and military dynamics have also shifted amid the fighting. While reports indicate Washington recently declined a Saudi request to strike the Houthis, the US State Department approved a $24.3 billion sale of 48 F-35 fighter jets to the kingdom to assist with long-term deterrence.

The United Nations reported that renewed fighting has displaced more than 112,000 individuals, with nearly 3,000 people fleeing across the sea to Djibouti. The conflict in Yemen initially began in 2014 when the Houthis seized Sanaa, prompting a Saudi-led military intervention in 2015. A fragile 2022 truce eventually collapsed in July when the Houthis permitted an Iranian aircraft to land in Yemen, defying Saudi airspace controls.
