An Aramco fuel tank near Riyadh King Khalid International Airport burst into flame Saturday morning, sending black smoke up over the runway, witnesses told AFP. The fire was followed by a series of explosions heard across the city, adding to the chaos. FlightRadar24 logged the incident as a maximum disruption, rating the airport at 5.0 on its index, and flagged dozens of cancellations and long delays. Saudi authorities had issued an overnight air‑raid alert the night before, a first since fighting in Yemen flared up this month, prompting emergency alerts across the capital. Emergency crews from the Interior Ministry are now securing the perimeter, while investigators from Aramco and the Civil Aviation Authority probe the cause; airlines are holding off on departures until the site is cleared.
