Pakistani military helicopters search for missing climbers

Pakistani army aviation helicopters which took off Monday with four Spanish rescuers onboard found no trace yet of a missing pair of European climbers on Nanga Parbat, the world's ninth highest mountain, official said.

Italian Daniele Nardi and Briton Tom Ballard, whose mother died on K2 in 1995, have been missing for a week on the summit known as "Killer Mountain."
"Unfortunately, no sign of climbers or a camp site was found during the aerial reconnaissance," Haidri said. Earlier, Haideri had told The Associated Press, "It's very difficult to survive in that condition" and that "It's a big challenge for (a) mountaineer to climb in winter."
