The president of F1 sponsor Total has been killed in a plane crash, the Russian news agency Ria Novosti reports.
The French oil multinational is closely aligned in Formula One with Renault-powered teams Red Bull and Lotus and the French driver Romain Grosjean.
Russia's Lifenews service also reports that Total's president, Christophe de Margerie, died in a plane crash at the Vnukovo airport in Moscow early on Tuesday.
"Together with the head of Total, all three crew members were killed," the news agency said, revealing that the Paris-bound jet crashed into a snow machine on the runway.
The airport confirmed that a Falcon 50 - a French-built, mid-sized corporate jet - had crashed.
“On behalf of the International Motor Sports Association, I offer our deepest condolences to family and friends of TOTAL CEO Christophe de Margerie, along with the other airplane passengers who tragically passed away yesterday in Russia,” said IMSA CEO Ed Bennett. “I also wish to extend condolences to the staff and employees at TOTAL on the loss of their dynamic leader in the oil industry. Our thoughts and prayers are with you.”
