In China Disagreement Means Jail

One of China's best known dissidents, Chen Guangcheng, has escaped from house arrest and has released a video addressed to Premier Wen Jiabao.

In it he makes three demands, including one that Mr Wen investigate what Mr Chen, who is blind, calls the brutal beating up of his family members.
Rights activists say Mr Chen slipped out of his home in Dongshigu town in Shandong province on Sunday.
His whereabouts are unclear, but supporters say he is safe in Beijing.
Unconfirmed reports say Mr Chen may have taken refuge in a diplomatic mission.
Mr Chen, 40, had been under house arrest since he was released from a four-year jail sentence in 2010.
