Protestors jumped the fence and stormed the track at the British Grand Prix as part of a dramatic start to the race.
The Silverstone race was reported to face the threat of a dangerous on-track protest that would have placed lives at risk. Police's worst fears came true when the protestors took to the track during the first lap.
But by then the race had already been stopped, after a huge incident at the first corner involving several drivers. In a statement, the FIA said: "We also confirm that after the red flag, several people attempted to enter the track. These people were immediately removed and the matter is now being dealt with by the local authorities."
Since that statement, climate activist group Just Stop Oil have taken responsibility for the protest. On Twitter, the group wrote: "A group of supporters of Just Stop Oil have stormed the track at #BritishGP2022 If you are more outraged about this disruption than our world being burnt before our eyes, then you need to get your priorities straight.
"We demand the government calls an immediate halt to new oil and gas projects in the UK and we will continue to disrupt sports, cultural events and oil until this demand is met. How many more young people have to step up before the government will listen?"
Northamptonshire Police had warned ahead of the race that they had received intelligence that a protest may take place. They warned that entering the track is "extremely dangerous", and urged those planning to interrupt the event to reconsider.
"We have received credible intelligence that a group of protestors are planning to disrupt the event and possibly invade the track on race day," said chief inspector Tom Thompson.
"First of all, I want to appeal directly to this group of people and strongly urge you to not put yourselves, the drivers, as well as the many marshals, volunteers and members of the public, at risk.
"Going onto a live racetrack is extremely dangerous – if you go ahead with this reckless plan you are jeopardising lives. Protesting is of course everyone's human right in this country and we are more than happy to speak with you to help you facilitate a peaceful protest at the circuit, we just please ask that you do not create a situation that puts lives in danger."
Also on the first lap, Zhou Guanyu's Alfa Romeo flipped over in a terrifying crash involving several drivers. Pierre Gasly made contact with George Russell's wheel, spinning the Mercedes and sending it crashing into Zhou.
The Alfa Romeo skidded across the tarmac upside-down and into the gravel, before flipping again to go over the crash barrier and into the catch fencing. After several minutes, it was confirmed that Zhou was conscious, though he was taken away on a stretcher.
