A former Tibetan Buddhist monk protested Chinese rule by killing himself through self-immolation this month, becoming the 100th person to do so inside Chinese-governed Tibet, according to reports on Wednesday by Tibet advocacy groups.

The Tibetan man, Lobsang Namgyal, 37, formerly of Kirti Monastery, set fire to himself on Feb. 3 in front of an office of the public security bureau in a county of Sichuan Province and died on the scene, according to Free Tibet, which is based in London. Free Tibet said in a news release that it had taken 10 days to confirm the self-immolation “because Tibetans are too frightened of Chinese state reprisals to speak about protests.”

Another advocacy group, the International Campaign for Tibet, reported that monks living in exile in India who had received word of the self-immolation had said that during the act, Mr. Lobsang Namgyal called for the long life of the Dalai Lama, the spiritual leader of the Tibetans.

The monks, who live in Dharamsala, India, the seat of the Tibetan government in exile, come from the same monastery as Mr. Lobsang Namgyal, and said he had been an exceptional student chosen to study for a Geshe degree, the highest qualification in Tibetan Buddhism.
