Xu is protesting against what he describes as inhumane treatment in prison, including lack of contact with his family

Concerns are growing about the health of Xu Zhiyong, China’s most prominent imprisoned human rights lawyer, who is thought to have been on hunger strike for nearly a month.

Xu, a scholar and leading figure in China’s embattled civil rights movement, started his hunger strike on 4 October, according to Chinese Human Rights Defenders, an NGO. He is protesting against what he describes as inhumane treatment in prison, including lack of contact with his family and intensive surveillance by other prisoners, according to reports released through his relatives.
