China has succeeded in stemming the flow of information out of Tibet in recent days, according to Tibetan activists in India who had relied on e-mails and mobile phone calls to piece together the extent of a Chinese military crackdown on pro-Tibet demonstrations.

Thousands of Tibetan exiles in India received live accounts as protests erupted in Tibet and largely Tibetan regions of China. About 120,000 Tibetans live in exile in India.
