Bad weather stalls K2 evacuation

(CNN) - A Pakistani rescue helicopter will try Wednesday morning to evacuate an Italian climber who survived a deadly ice avalanche four days ago on K2, the world's second highest mountain.

The chopper was unable to attempt the high-altitude operation Tuesday because of "extremely poor weather," Askari Aviation said on its Web site.

The survivor, Marco Confortola, arrived Tuesday at K2's base camp, where he is being treated by doctors for frostbite on his feet, according to updates of the rescue operation provided by his expedition team's Web site. Two other survivors, both Dutch men, were flown to a hospital in Pakistan on Monday, according to Shahzad Qaiser, secretary of the Pakistani Ministry of Tourism. They are also suffering from frostbite.

Ten out of 17 climbers died after they had reached the peak - either in the avalanche or as they tried to climb down in the icy conditions. One rescuer also died.
