Two Japanese climbers went missing while attempting to scale the 8,611-metre-tall K2 peak, the second-highest mountain in the world, on Saturday morning.
Shigar Deputy Commissioner (DC) Waliullah Falahi told Dawn.com that Japanese climbers Kazuya Hirade and Kenro Nakajima fell down from a height of 7,500m, west of K2.
He said Pakistan Army helicopters conducted a search operation in the area, adding that two military helicopters flew from Skardu and searched for the climbers at the peak.
