Following a pro-independence riot in which about 100 people attacked Chinese policemen and government officials in the ethnically Tibetan town of La'gyab in Qinghai Province, the government arrested approximately 93 Tibetan Buddhist monks.
Apparently, the riot began when a pro-independence Tibetan monk escaped from prison. According to Chinese authorities, the monk is still at large. According to a Tibetan website, however, he has committed suicide. A further two laypeople are also being held under arrest (BBC).
