China has been grappling to quell unrest in several Tibetan towns and villages in the country's west, after Buddhist monk-led demonstrations in Tibet's capital Lhasa turned violent on Friday. The government in recent days has asked foreigners in Tibet to leave and has suspended approving travel permits to the Himalayan region. REUTERS/David Gray (CHINA)
