The famous Pakistani mountaineer Sirbaz Khan achieved another landmark in the history of high altitude climbing as he successfully summarized the world’s third highest mountain, Kangchenjunga, Sunday morning.

Khan reached the top of the 8,586 meters high kangchenjunga at. 05:00 NEPAL TIME. What makes this business extraordinary is that he achieved it without the use of additional oxygen – a defining moment in Pakistan’s mountaineering. With this latest performance, Sirbaz Khan becomes the first Pakistani and one of the very few elite mountaineers around the world to summit all the 14 peaks over 8,000 meters – known as ‘eight thousands’ – without supplementary oxygen support.

Previously, he has scaled Everest, 8,848 m; K2, 8.611m; Lhotse, 8,516 m; Makalu, 8,485 m; Cho Oyu, 8.188 m; Dhaulagiri, 8,167 m; Manaslu, 8,163 m; Nanga Parbat, 8,126 m; Annapurna I, 8.091m; Gasherbrum I, 8,080 m; Wide top, 8.051 m; Gasherbrum II, 8,035 m; and Shishapangma, 8.027m.

Sirbaz Khan’s journey to this historic milestone spans a decade. His performance on Sunday not only cemented his place among the greatest mountaineers of all time, but also brings tremendous pride to the Pakistan population.

Khan comes from Gilgit-Baltistan (GB). His performance was made in the spirit of pure alpine climbing – minimal gear, no fixed rope or camps set by sherpas and no oxygen support.

“Sirbaz Khan has made the whole nation proud. To end all 14 eight thousands without oxygen is a rare and heroic performance. He is a symbol of Pakistani resilience, skill and courage at the highest peaks in the world,” said Karrar Haidri, secretary of the Alpine Club of Pakistan, in a greeting of the message to Khan.
