Sources in the Tibetan exile community say at least six Tibetans were injured when Chinese paramilitary police fired on a crowd that was attempting to commemorate the Dalai Lama's birthday in a volatile part of western China.

Authorities in Sichuan province's Daofu county did not answer phone calls Monday or immediately hung up on a reporter seeking confirmation of the incident.

Tawu Lobsang Jinpa, a former prisoner living in exile in India, said he was told of Saturday's shooting by a Tibetan Buddhist monk who was caring for one of those injured in the Saturday clash. The London-based International Campaign for Tibet says it confirmed the shooting, in which one monk suffered a serious head wound.

They both said police fired at about 500 Tibetans attempting to hold commemorations.
