China is deliberately separating Muslim children from their families, faith and language in its far western region of Xinjiang, according to new research.
At the same time as hundreds of thousands of adults are being detained in giant camps, a rapid, large-scale campaign to build boarding schools is under way.
Based on publicly available documents, and backed up by dozens of interviews with family members overseas, the BBC has gathered some of the most comprehensive evidence to date about what is happening to children in the region.
Records show that in one township alone more than 400 children have lost not just one but both parents to some form of internment, either in the camps or in prison.
Alongside the efforts to transform the identity of Xinjiang's adults, the evidence points to a parallel campaign to systematically remove children from their roots.
New research commissioned by the BBC sheds light on what is really happening to these children and many thousands of others.
Dr Adrian Zenz is a German researcher widely credited with exposing the full extent of China's mass detentions of adult Muslims in Xinjiang. Based on publicly available official documents, his report paints a picture of an unprecedented school expansion drive in Xinjiang.
Campuses have been enlarged, new dormitories built and capacity increased on a massive scale. Significantly, the state has been growing its ability to care full-time for large numbers of children at precisely the same time as it has been building the detention camps.
And it appears to be targeted at precisely the same ethnic groups. source: bbc
