The red flag was waved after just the second lap when Juan Manuel Correa, Anthoine Hubert and Marino Sato were involved in a horrific crash.
Replays appeared to show Hubert crash hard into the barriers on the right and bounced back into the track where Correa had no time to avoid a collision.
Marino Sato was also involved in the accident, but he was spotted walking away from his car.
The remaining cars were taken back to the pit lane where a decision was soon made that the race would not be restarted.
Spectators spoke of how ambulances were quick to approach the scene while fans were vacating the area.
