Two more mountaineers have died on Mount Everest after crowds of people became stuck in a queue leading to the summit of the world’s highest mountain. The deaths of an Irish and a British climber on Mount Everest took the toll from a deadly week on the world’s highest peak to 10, expedition organisers said yesterday. British climber Robin Fisher, 44, reached the summit yesterday morning but collapsed when he had got just 150 metres back down the slope. “Our guides tried to help but he died soon after,” Murari Sharma of Everest Parivar Expedition told AFP.
