A track marshal has died after being injured in an accident during the Canadian Grand Prix.
The worker was killed after being run over by a mobile crane that was removing the Sauber of Esteban Gutierrez from the side of the track after he crashed in the closing stages.
It is the first death in Formula One since another marshal, Graham Beveridge, was fatally injured in the 2001 Australian Grand Prix.
The news was confirmed by motor sport's world governing body, the International Automobile Federation (FIA), almost four hours after the end of the race at Montreal's Circuit Gilles Villeneuve.
The race was won by Red Bull's Sebastian Vettel.
The FIA released a statement confirming that the marshal, a member of the Notre Dame Automobile Club, had died from his injuries in a Montreal.
They did not identify the marshal but said he was "the victim of an unfortunate accident."
"The worker was helping to recover a car which had stopped during the race," said the statement. "The recovery vehicle had lifted the car to return it to the pits and while doing this the worker dropped his radio and attempted to pick it up.
"As he did this, he stumbled and was hit and run over by the recovery vehicle."
The FIA said the worker was transferred by helicopter to the Sacre-Coeur hospital in Montreal for treatment but his injuries were too severe and he died.
