Trouble in Tibet

Riot police patrol on a street in Tongren, in China's Qinghai province Monday March 17, 2008. Protests spread from Tibet into three neighboring provinces as Tibetans defied a Chinese government crackdown. The Tibetan spiritual leader the Dalai Lama, the public voice of a region now largely sealed off from the rest of the world, called on Sunday for an international investigation into the crackdown against protesters in his homeland, which he said is facing a "cultural genocide."
