Relatives of Chinese activist Li Wangyang, found dead in a hospital earlier this week, say his body has been cremated, against their will. They question official accounts that he committed suicide. 

The announcement follows controversy over another high-profile Chinese dissident, Chen Guangchen, who managed to leave the country last month after a dramatic escape from house arrest.

While Chen is now free, his nephew is still in detention and the crackdown on those fighting for more rights continues.
