Formula 1 practice was delayed at the Saudi Arabian Grand Prix after a fire erupted near the track in Jeddah.
Team bosses and drivers were called to a meeting with F1 president Stefano Domenicali before second practice, which was delayed by 15 minutes.
Smoke billowed across the track amid reports that a fire had broken out at an oil depot 12 miles from the circuit.
Yemen’s Houti rebels claimed responsibility for an attack, according to the Associated Press.
Red Bull driver Max Verstappen reported to his team during the first session earlier on Friday that he could smell smoke.
“I smell a bit of a burning feeling,” said the Dutchman. “I am not sure if it is my car, or another car.”
His engineer Gianpiero Lambiase replied: “We are happy it is not your car.”
The second practice session started at 18:15 GMT.
There is due to be a second meeting to discuss the situation after the session.
