VIDEO: Jules Bianchi F1 crash footage
The Frenchman suffered severe head injuries and is in a critical condition in hospital following Sunday's crash in wet weather conditions.
The footage shows men working at a recovery truck, lifting another vehicle thought to be that of Germany's Adrian Sutil who crashed earlier.
Bianchi's car is then seen crashing at high speed into the truck.
The video is believed to have been captured by a fan who attended the race.
The last time there was a major accident on a Formula One circuit was 20 years ago when Brazil's Ayrton Senna died when his car crashed at the San Marino Grand Prix.
A day earlier, Austrian driver, Roland Ratzenberger, died in hospital shortly after crashing during qualifying at San Marino.
Fans and fellow racers have taken to social media to wish Bianchi well.
God be with the family, friends and especially with @Jules_Bianchi , giving strength! Get well soon! #PrayForJules 🙏🙏 pic.twitter.com/MKHz48qk7L
