In China’s northwestern Xinjiang region, more than one million ethnic Uighurs are believed to be held in internment camps. The authorities call them "re-education through labour camps", but victims say the reality is forced indoctrination for Uighurs held in alarming conditions.Human rights groups are calling it the largest mass incarceration of the 21st century. In the Chinese province of Xinjiang - three times the size of France - houses, streets and sometimes entire villages have been emptied of their inhabitants. Accused of religious extremism, they are sent to "re-education through labour camps" or“vocational training” centres, as the authorities call them, without any form of trial. According UN experts, more than one million Uighur citizens - members of a Turkic-speaking, Muslim minority - are held in these camps, which are in reality huge prisons. Detainees are reportedly tortured and brainwashed by the Communist Party.

In the name of "fighting terrorism" - attacks blamed on Uighurs have killed hundreds in recent years - China has turned the whole of Xinjiang province into a gigantic police state. Surveillance cameras are everywhere: at the entrance to schools, supermarkets or even train stations. The police and army patrol the whole territory. Searches and identity checks are systematic. Craftsman, singer, cook, teacher or taxi driver -- no one is spared.
