Nepalese team claim first winter ascent of Pakistan's K2
Dozens of mountaineers have been competing over the past few weeks to summit the world's second highest mountain, the last peak above 8,000 metres to be topped in wintertime.
"WE DID IT" tweeted Seven Summit Treks.
"The Karakorum's 'Savage Mountain' been summited in most dangerous season: winter. Nepalese climbers finally reached the summit of Mt K2 this afternoon at 17:00 local time."
Since the maiden attempt in 1987-1988, just a handful of winter expeditions have been attempted on the storied 8,611-metre (28,250-feet) mountain in the Karakoram range along the Chinese border.
None had got higher than 7,650 metres until Saturday when the good conditions allowed the climbers to push ahead.
This winter an unprecedented four teams totalling around 60 climbers converged on the mountain, more than all the previous expeditions put together.
The 10 Nepalese climbers had earlier been spread across the different teams, but formed a new group in order to claim the feat in Nepal's name.
Known as the "savage mountain", winds on the peak can blow at more than 200 kilometres per hour (125 miles per hour) and temperatures drop to minus 60 degrees Celsius (minus 76 Fahrenheit).
