China calls it 're-education' and a clampdown on Islamic terror; others call it genocide, with disturbing parallels to the events of the Holocaust. Roy Jenkins reports on the plight of the Uyghur people of Xinjiang, or East Turkestan in China. With a language and culture quite distinct from that of the Han Chinese people, it's now estimated that 1M people or more are being detained in 're-education camps', incarcerated on grounds of race, culture and religion. Roy Jenkins talks to one Uyghur exile, Rahima Mahmut, who is campaigning on behalf of her people, despite the obvious dangers to her own safety and that of her family back in China. She has lost contact with her brothers and sisters since the 2016 clampdown on Uyghurs. Her story has caught the attention of a prominent Jewish human rights campaigner, Mia Hasenson-Gross, and there are now widening calls for bringing economic and moral pressure to bear on the Chinese government.
