A group of ten Nepalese mountaineers have been the first in the world to climb to the world’s second-highest K2 peak in the winter, the BBC told Saturday.

The 8,611-meter-high K2 peak is located on the Pakistan-China border.

Of the world’s fourteen mountains over eight kilometers high, it is considered by far the most difficult to climb in winter.

The group reached the top on Saturday afternoon Finnish time.

Since the first attempt at winter climbing in 1987-1988, only a handful of climbers have tried again. Prior to Saturday's successful attempt, none had reached a height higher than 7,650 meters.
