Rescuers from the Aosta region in northwestern Italy said that two women were frozen in the Alps at an altitude of more than 4,000 meters near the border between Italy and Switzerland.
The man who was with the injured woman was taken to a Swiss hospital on Saturday night. He has hypothermia and frostbite.
The three of them are on the Rosa Mountain in the Pennine Alps, the highest peak is Dufoss, which is more than 4630 meters above sea level.
The rescue agency said they were listed as missing persons. They found them on the Italian side of the Pyramid of Vincent, a slightly lower peak, and took them to a hut.
However, extreme weather conditions and strong winds made their rescue operations difficult. The helicopter can only land when night falls.
Rescuers tried to bring the two women back to life, but they were unsuccessful.
