Two of the group of Tibetan former political prisoners known as the 'Drapchi singing nuns' have just arrived safely in exile after escaping from Tibet across the Himalayas. The two nuns are Rigzin Choekyi, who served 12 years in prison, and Lhundrub Zangmo, who served nine years. Both women were among a group of nuns, together with Phuntsog Nyidron and Ngawang Sangdrol, whose sentences were extended after they secretly recorded songs about the Dalai Lama and Tibet's future on a tape cassette that was smuggled out of prison and reached the West.
