A British climber has died while attempting to climb Nepals Mount Manaslu, the worlds eighth tallest peak, the expedition organiser said on Monday.The mountaineer fell ill at the last camp before the 8,156 metre summit and died as he was being taken down the mountain.We have confirmed that one person, a British national, has died between camp two and three. He went up to camp four but was not feeling well and was descending with our staff,said Iswari Poudel, head of the Himalayan Guides Nepal climbing agency.The agency did not name the man.The body is still in the same area and we are getting permission from his family for further action.Nepal granted permits to 255 climbers this autumn season for Manaslu, a record number.At least 13 climbers and their sherpa guides have reached the top this month, while heavy snow has left other teams waiting at base camp for clear weather.Last year, 171 people summited Manaslu, according to the Himalayan Database, an archive of expeditions in Nepal.
