GENEVA (AP) — A long-awaited report from the U.N. human rights office says China’s discriminatory detention of Uyghurs and other mostly Muslim ethnic groups in the western region of Xinjiang may constitute crimes against humanity. The report release Wednesday calls for an urgent international response over allegations of torture and other rights violations in Beijing’s campaign to root out terrorism in Xinjiang. U.N. human rights chief Michelle Bachelet brushed aside China’s vocal calls for her office not to release the report, which was months in the making. Beijing contends the report is part of a Western campaign to smear China’s reputation.
