A four-year-old British girl was found alive underneath the bodies of her parents around eight hours after a brutal massacre in the Alps, French authorities have said.
And a seven-year-old girl, thought to be her sister, was found violently beaten and is fighting for her life.
The four-year-old lay undiscovered as police waited for forensic experts to arrive at the scene from Paris.
A man and two women - believed to be the girls' mother, father and an older relative - were in the British-registered BMW, which was riddled with bullets.
The man was named by French media as Saad al-Hilli, from Claygate, near Esher in Surrey.
Mr al-Hilli, in his fifties, had been behind the wheel at the time of the attack.
Surrey Police said it was assisting the French authorities and liaising with the Foreign and Commonwealth Office.
