The Chinese government on Sunday blocked Internet users in the country from accessing the video-sharing website YouTube after videos of a recent government crackdown on Tibetan protesters challenging Chinese rule were posted on the site. The protests over degradation of Tibetan culture and a flood of new Chinese immigrants into the region escalated into violence in the capital Lhasa on Friday with reports that as many as 80 protesters had been killed. Exiled Tibetan spiritual leader the Dalai Lama on Sunday deplored the use of violence by both the protesters and the government, but said that the region is facing “cultural genocide”. AP has more.
