Pakistani climbs world’s 4th highest peak without supporting oxygen

Sirbaz Khan has become the first Pakistani to successfully ascend the world’s fourth highest mountain, Mount Lhotse’s 8,516 meters high peak on Nepal-Tibet border, without using supplemental oxygen. Sirbaz completed the summit on May 14 at 9:47 am, and his team was the first to scale Lhotse this year as they fixed ropes along the peak to open the mountain for other climbers.
