The chief executive of French oil company Total, Christophe de Margerie has died in an air crash in Moscow.
The private plane he was traveling on collided with a snow-plough on take-off . Three crew members also died.
Witnesses said the aircraft burst into flames on impact. Wreckage was scattered up to 200 metres away from the initial crash site.
Earlier in the day bad weather conditions had meant at least 18 planes had to be diverted from Vnukovo to other Moscow airports.
Sixty-three-year-old de Margerie who had been chief executive of Europe’s third largest oil company since 2007, had been attending a Russian government meeting on foreign investment.
Total is one of the top foreign investors in Russia but it has been badly hit by the worsening relations between Moscow and the West over the Ukraine crisis.
The oil giant is France’s second-biggest listed company with a market value of 102 billion euros.
