Two skiers from France and Belgium were killed in avalanches in the French Alps on Sunday while three other people remain missing, a local official said.
The deaths add to the toll in the French mountains from avalanches since Friday.
Interior Minister Gerard Collomb, on Twitter, urged all those taking part in winter sports to act “with the utmost caution.”
It is essential to follow the signs put up by local authorities “to avoid putting yourself in danger and endangering rescue teams”.
Alors que de nombreuses avalanches ont endeuillé nos massifs, j'appelle tous ceux qui pratiquent les sports d'hiver à la plus grande prudence.
Suivre les consignes des autorités est indispensable pour ne pas se mettre en danger. Et ne pas mettre en danger nos équipes de secours. pic.twitter.com/xZj6JtwQog
