PARIS (AP) — French rescue services have found a fifth body after an avalanche southwest of Mont Blanc in the French Alps, local authorities said Monday.

The avalanche occurred midday Sunday on the Armancette glacier, which is near the town and ski resort of Les Contamines-Montjoie.

Emmanuel Coquand, a spokesman for authorities in the Haute-Savoie region, said he could not confirm the identity of the victims, but they were ski-country skiing when the avalanche struck.

Coquand said the avalanche had been extensive, covering an area of ​​one kilometer by 500 meters (half a mile by 550 yards) at an altitude of 3,500 meters (11,482 feet) and that its causes were being investigated.

Bonneville prosecutors investigating the incident did not immediately respond to questions about the identity of those killed in the avalanche, but local media said two of the dead were mountain guides.
