DIJON, France (AFP)—Avalanches killed two skiers in the French Alps on Monday, authorities said, following the deaths of two off-piste tourers in a separate slide at the weekend.

A 38-year-old man was killed in Saint-Agnes near Grenoble, local police said. A skier he was with was unharmed.

Another man, in his early 30s, was the victim of a “very large avalanche” while skiing in an off-piste area near the village of Montgenevre, Gap prosecutor Marion Lozac’hmeur told AFP. Another skier with the victim was also unharmed, she added.

Their deaths come after an avalanche killed two off-piste ski tourers in the French Alps on Saturday, near Saint-Veran, known as the highest village in the French Alps.

The two victims were part of a group of four unguided skiers when an avalanche swept down the north side of the Tete de Longet mountain peak.

Avalanches have already claimed the lives of at least 20 skiers across the French, Swiss, Italian and Austrian Alps so far this season.
