Cheruiyot Kirui, a Kenyan climber, and Nawang Sherpa, his guide, had not been seen since this morning, when they were at an altitude of more than 8,000 metres, Himalayan newspaper reports.
Mingma Sherpa, Chairman of Seven Summit Treks who’re the organizers of the climbing expedition, stated that Cheruiyot Kirui, who attempted to mount Everest without the use of supplementary oxygen, remained out of communication from Bishop Rock, which is just a few metres below the summit point.
It was reported by Sherpa that Nawang was quoted as claiming that Kirui, who wanted to climb Everest without using any supplemental oxygen, exhibited an aberrant behaviour with his guide. After then, the two individuals lost touch with one another.
