A search operation was underway on Friday to locate 10 climbers, including renowned Nepali mountaineer Nirmal Purja and Pakistani climber Sohail Sakhi, who went missing on Broad Peak a day earlier after an avalanche struck around midday. The Alpine Club of Pakistan (ACP) said that the missing climbers included six Nepalese climbers, a Pakistani, an Omani, an American and a climber from China. The climbers from Nepal were identified as Purja, Pur Bahadur Gurung, Kili Pemba Sherpa, Nima Sherpa, Nawang Thindu Sherpa and Gyalu Sherpa. It identified the remaining climbers as Nadhira Ahmed Abdullah Al Harthy from Oman, Sakhi from Pakistan, Wang Zhong from China and Mallory Geis from the United States. In a statement issued on Friday, ACP Senior Vice President Karrar Haidri said two Pakistan Army Aviation rescue helicopters, carrying rescue personnel and additional specialised equipment, had been dispatched to support the ongoing search and rescue operation. The statement said ACP’s Major General Irfan Arshad, HI(M), along with the club’s senior leadership, remained in constant contact with the highest government authorities and relevant agencies to facilitate the rescue operation. “Every possible effort is being made to ensure that helicopter support and all available rescue resources are mobilised at the earliest opportunity, subject to weather and operational conditions,” it added. The club said it was closely monitoring the situation and coordinating with all relevant stakeholders while expressing solidarity with the climbers’ families and the international mountaineering community. ACP’s General Secretary Ayaz Shigri told Dawn that several expedition teams had jointly begun their summit push before the incident. He said GPS locations received from some of the missing climbers indicated that the avalanche had swept the group about 1,000 metres downhill, leaving them trapped. Shigri said helicopter-assisted rescue operations were expected to begin on Friday morning. He said there were also fears that some local high-altitude porters might have been affected by the avalanche. “We pray for the safety of all the climbers. It is a big incident,” he said. Purja, 43, who served with Britain’s Brigade of Gurkhas before joining the Special Boat Squadron of the Royal Marines, has broken multiple climbing records since becoming a full-time mountaineer and tour guide. He climbed all 14 “eight-thousanders” (peaks above 8,000 metres, or 26,000 feet) in six months and six days between April and October 2019 — then a record. In 2021, Purja completed the first winter ascent of K2 along with a team of nine other Nepalese climbers. Sakhi, who hails from Hunza, had successfully summited Kanchenjunga (8,58­6m), the world’s 3rd highest mountain, in Nepal earlier in May. He had previously scaled K2, Nanga Parbat, Gasherbrum I and Gasherbrum II without supplemental oxygen, establishing himself among the country’s strongest high-altitude climbers.
