From China National News:
A Chinese protection force and scores of British police ringed Olympic torch carriers on their ceremonial run through London Sunday but could not prevent a high-profile pro-Tibet demonstration from frequently disrupting the event.
The police made at least 10 arrests after activists protesting China’s crackdown on pro-independence Buddhist monks in Tibet unsuccessfully tried to snuff out and snatch the Olympic flame at two changeover spots during the 31-mile procession.
China’s ambassador to Britain Fu Ying had to hastily change plans to carry the torch – she was bundled into a car and driven away from central London, but then appeared in the China Town area to take the torch.
