KATHMANDU: Two Indian mountaineers who summited Everest have died while descending, an official said on Friday. The climbers, identified as Arun Kumar Tiwari and Sandeep Are, were exhausted while they were coming down from the peak and could not be saved despite the best efforts of their guides, said Rishi Bhandari, secretary general of the Expedition Operators Association of Nepal.It appears that Are summited on Wednesday and Tiwari on Thursday around 5.30 pm, Bhandari said. The guides ‘worked really hard’ but were not able to save them, he said. Tiwari died near the Hillary Step, just below the summit, after falling ill during his descent on Thursday evening while being assisted by four Sherpa climbers, said Nivesh Karki, Director at Pioneer Adventures, which organised the expedition.
