A team of Nepalese mountaineers on Saturday became the world's first to scale K2, the world's second-highest mountain, in winter, a Pakistani alpine group said.

Of the 14 mountains in the world that rise above 8,000 meters, only 8,611-meter K2 had not been scaled in winter.

The peak in northern Pakistan near China is known for its unforgiving conditions and is often referred to as the Savage Mountain.

A group of 10 Nepali climbers reached the summit Saturday, the Alpine Club of Pakistan confirmed.

"The impossible is made possible!" Nirmal Purja, one of the climbers, tweeted. "History made for mankind, History made for Nepal!"
