Avalanches have struck high on the slopes of the Tibetan mountain Shishapangma as more than 50 climbers were making a push for the summit, killing an American and Nepalese mountaineer, China's state-run Xinhua news agency said, Report informs via Reuters.
Shishapangma, at just over 8,000 metres, is the world's 14th tallest peak. It is widely regarded as one of the easier mountains of that height, known among climbers as the "eight-thousanders".
Two avalanches hit its slopes at elevations of 7,600 metres and 8,000 metres on Saturday, killing American climber Anna Gutu and Nepalese guide Mingmar Sherpa, Xinhua reported on Sunday.
Another American climber, Gina Marie Rzucidlo, and her Nepalese guide, Tenjen Sherpa, were missing, Xinhua said.
Tenjen Sherpa was the guide for Norway's Kristin Harila when they climbed K2 in Pakistan in July to become the world's fastest climbers to scale all of the 14 peaks over 8,000 metres.
A total of 52 climbers were pushing for the summit when the avalanches hit, including from the United States, Britain, Romania, Albania, Italy, Japan and Pakistan, Xinhua said.
All climbing activity on Shishapangma was suspended because of the unstable snow conditions.
Two Pakistani climbers narrowly escaped the avalanches on Saturday after calling off their summit bid because of poor weather despite coming within a few hundred metres of the peak, Pakistani media reported.
Had one of the Pakistani climbers, Sirbaz Khan, reached the top of Shishapangma he would have become the first Pakistani to summit all 14 mountains over 8,000 metres.
More than 300 successful summits of Shishapangma have been logged to date, with under 10% of climbers who tried to reach the top dying in their attempts, according to private estimates.
That compares with the nearly 30% fatality rate for Nepal's Annapurna I, one of the world's most dangerous peaks.
