United Nations human rights chief Michelle Bachelet has called on China to accept observers in the Xinjiang Uyghur Autonomous Region. Bachelet made the request on Monday. Her appeal came as Human Rights Watch released a report on the area’s Turkic, mostly Uyghur minority population. The group's report says that Uyghurs and other Muslims in Xinjiang face unjustified detention, restrictions on religious activities and “forced political indoctrination” as part of a security campaign by China’s government. A UN rights group said last month it had received reports that up to one million Uighurs may be held in extra-legal re-education camps in far western China. The group called for their release. China has rejected the claims of internment camps. It accuses outsiders of causing unrest in the area.
