Motor racing's governing body, the FIA, has launched an investigation into the accident which killed Formula 2 racer Anthoine Hubert on Saturday.
Hubert died after being hit by another driver at high-speed after losing control of his car at the fearsome Raidillon corner at the Spa-Francorchamps circuit in Belgium. The other driver, American Juan Manuel Correa, remains in intensive care after suffered leg fractures and a minor spinal injury.
The incident led to the cancellation of both F2 races scheduled for the weekend - Formula One's Belgian Grand Prix went ahead but only after a minute's silence was held for Hubert before the start.
