Marco Simoncelli, 24, had his helmet knocked off and was hit by both other riders.

American rider Colin Edwards also fell and dislocated his shoulder – while Marco Simoncelli’s fellow Italian, Valentino Rossi was able to return to the pits.

Marco Simoncelli lay motionless on the track after the impact, while the race was immediately red-flagged.

At first officials were looking to restart the race before the extent of Marco Simoncelli’s injuries became clear.

Eventually, the race was cancelled amid confusion in the grandstand, with fans throwing bottles to show their initial displeasure.

Marco Simoncelli’s death is the first fatality in MotoGP since Japan’s Daijiro Katoh died from injuries sustained at the 2003 Japanese GP while, last year, Japan’s Shoya Tomizawa died in a similar crash to Simoncelli in a Moto2 race in San Marino.

Marco Simoncelli’s death comes a week after British IndyCar driver Dan Wheldon was killed in Las Vegas following a crash.
