London 2012 Olympic swimming champion Camille Muffat and Beijing 2008 boxing medallist Alexis Vastine are among 10 people to have tragically died in a helicopter crash in Argentina, it has been confirmed.
In total, eight French nationals and two Argentinean pilots were killed after two helicopters collided, including Muffat and Vastine, who won a light welterweight bronze medal at Beijing 2008, as well as gold at the 2005 Mediterranean Games.
Sailor Florence Arthaud, a solo yachtswoman who first gained fame for winning a race across the Atlantic Ocean as a 17-year-old before triumphing in the 1997 Transpacific race across the Pacific, was also involved.
All were involved in the filming of television survival show, "Dropped", in which celebrities are flown into hazardous terrain by helicopter before being filmed as they attempt to find food and shelter.
No details have yet emerged as to what caused the accident, but tributes have already been paid across France, as well as the sports world.
These tributes were led by French President Francois Hollande, who said: "The sudden death of our fellow French nationals is a cause of immense sadness".
In a statement this morning, International Olympic Committee (IOC) President Thomas Bach claimed he was "shocked by this sad news".
Bach added: "Our thoughts are with the families and friends of these great athletes who have left us.

"They were all not only champions in their sport but also contributed greatly as role models.
"The Olympic Movement mourns with their families and friends, their fellow athletes, the French National Olympic Committee and with France."
The Olympic flag will be flown at half-mast for three days at the IOC Headquarters to honour these great champions,Bach added.

"She was and will remain a role model for the youth in France and a true inspiration for all those aiming at becoming successful swimmers."

He will "be sorely missed by all involved in the sport and beyond", it added.
The International Sailing Federation expressed its "sincere condolence to Arthaud's family and friends in the sailing world and all those affected", in a glowing tribute of her record-breaking achievements.
