A track marshal has died after being injured in an accident during the Canadian Grand Prix.
The news was confirmed by motor sport's world governing body, the FIA, almost four hours after the end of the race at Montreal's Circuit Gilles Villeneuve:
It is the first death in Formula One since another marshal, Graham Beveridge, was fatally injured in the 2001 Australian Grand Prix.
In 2001 in Melbourne, Beveridge was struck by a flying wheel from Jacques Villeneuve's BAR-Honda that had passed through a gap in the safety fence.
A few months previously at the 2000 Italian Grand Prix in Monza, volunteer firefighter Paolo Ghislimberti died from head and chest injuries after being struck by a loose wheel.
