China's "arbitrary and discriminatory detention" of Uyghurs and other Muslims in its Xinjiang region may constitute crimes against humanity, the outgoing U.N. human rights chief said in a long-awaited report on Wednesday.
U.N. High Commissioner for Human Rights Michelle Bachelet, who some diplomats and rights groups have criticized as soft on China, released the report just minutes before her four-year term ended. She visited China in May.
