Four people have been shot dead and a young girl is fighting for her life after a British-registered BMW was blasted with bullets at a remote car park in the French Alps.
The suspected assassination happened in a forested area near the village of Chevaline, near Lake Annecy, in the Haute-Savoie region.
Three adults were found dead inside the 4X4 vehicle, which had UK licence plates. A man was found at the wheel, and two women in the back.
A young girl was found near the car, and initial reports said she died later from her injuries. A local prosecutor has now said she is in a critical condition in hospital in the city of Grenoble.
The body of a male cyclist was also found nearby.
The girl is believed to be around seven-years-old and was shot at least three times, according to reports quoting police sources.
The four bodies and the BMW were riddled with bullets in what looked like a "deliberate assassination", the reports added.
It is understood that no weapons were found by officers, and dozens of shell casings were found near the BMW.
The gruesome scene was discovered by another cyclist who is in shock.
Stephane Bouchet, from local newspaper Le Dauphine Libere, told Sky News a witness two miles from the car park saw a car driving very fast away from the scene around the time of the shooting.
Local prosecutor Eric Maillaud said: "There is a crime scene with several dead, and fortunately we see more scenes like this in the films than real life.
"There are four, if not five, victims killed by bullets. It's an extremely serious case on a human level."
He said post-mortems are due to be carried out on Thursday or Friday.
Local journalist Leila Lamnaouer told Sky News: "The cyclist discovered the bodies at around 4pm this afternoon.
"It's a very quiet place, a lot of people go there to spend holidays near the lake."
There are 60 police officers involved in the operation, and the nearby area has been sealed off as investigations continue.
A Foreign Office spokesman said: "We are aware of the reports of the shooting and we are looking into these urgently."
Lake Annecy, known as the "little Venice of the Alps", is a popular area for swimming and water sports.
