A British climber has died while attempting to climb Nepal's Mount Manaslu, the world's eighth tallest peak. <br/><br/>The expedition organiser said today that the mountaineer fell ill at the last camp before the 8,156-metre summit and died as he was being taken down the mountain. Nepal granted permits to 255 climbers this autumn season for Manaslu. <br/><br/>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.<br/>
