Five people have been killed in a helicopter crash in the French Alps on Tuesday, French President Emmanuel Macron said.
A sixth passenger is injured and fighting for his life, officials added.
The helicopter was carrying an air rescue crew on a training mission when it went down at an altitude of 1,800 meters, local authorities said.
The pilot of the aircraft, which also had another pilot on board as well as two winch operators and two mountain rescue workers, was able to eject and give the alert.
Three helicopters were dispatched but had been unable to reach the accident site due to fog while rescue teams were also trying to approach by ground, the Savoie prefecture said in a statement.
France's air accident bureau said separately that it had opened an investigation and would dispatch a team to the site.
