From BBC News:
Chinese police have detained several people after pro-Tibet protests in south-west China, campaign groups say.
The protests flared at the weekend in Litang county, in Sichuan province.
A number of Tibetans were beaten and 21 detained, the Free Tibet group and the Tibetan Centre for Human Rights and Democracy (TCHRD) said.
The incident comes ahead of the 50th anniversary of the exile of the Dalai Lama, the Tibetan spiritual leader, and follows violent protests last year.
