Free Tibet, a London-based advocacy group, has launched a campaign urging China to free eight Tibetan singers. It is calling for the release of Lolo, Kalsang Yarphel, Pema Tinley, Chakdor, Shawo Tashi, Ugyen Tenzin, Achol Phulshung and Choksal, all taken in custody over the last two years. Trinley Tsekar and Gonpo Tenzin, arrested last month, will be included in the campaign if they are not released shortly.
