Danish racing driver Allan Simonsen has died as a result of injuries sustained in a crash during the Le Mans 24 Hours, race organisers have confirmed.
Simonsen was contesting the GTE Am category at the wheel of an Aston Martin when he crashed heavily at the Tertre Rouge.
The 34-year-old was immediately attended to by doctors from the race's medical team.
"In a serious condition, Allan Simonsen was transferred immediately to the Circuit Medical Centre where he died soon after due to his injuries," a statement from the race organisers confirmed.
David Richards, the principal of the Aston Martin Racing team, immediately broke the news to Simonsen's family, the statement added.
It continued: "The Automobile Club de l'Ouest wishes to express its great sadness following this incident, and extends its deepest condolences to the family and those close to Allan Simonsen.
"The Automobile Club de l'Ouest will make no further statement while the exact reasons for the accident are still being wholly determined."
Simonsen was an experienced Le Mans campaigner and was racing for the seventh time at La Sarthe.
The race was less than 10 minutes old when the accident occurred.
Only two days earlier Simonsen, along with Danish team-mates Christoffer Nygaard and Kristian Poulsen, was celebrating after the number 95 Aston claimed pole position in the GTE Am class.
