Former motor racing world champion Michael Schumacher has suffered head injuries in a skiing accident.
It happened while the 44-year-old was skiing in the French resort of Meribel in the popular Three Valleys area.
It is understood he was wearing a helmet when he hit his head on a rock in an off-piste area and that he did not lose consciousness.
He was airlifted off the mountain and is now at a hospital in Grenoble.
