Nury Turkel was born in a Chinese re-education camp in the Xinjiang Uyghur Autonomous Region, managing to flee China in 1995 to attend university in the United States. Becoming the first Uyghur to receive an American law degree, Nury Turkel went on to become a human rights attorney and activist for Uyghur people. In recent years, China's repression of Uyghur Muslims has intensified, most visibly through the construction of a series of re-education centres in Xinjiang. This was further exposed last week, when a cache of hacked data and photographs from police computers, now called the Xinjiang Police Files, were published online. It revealed in unprecedented detail, China's brutal use of re-education camps and prisons as a system of mass detention for Uyghurs. It's estimated between one and two million Uyghurs are detained in the Xinjiang facilities. The documents also uncovered a "shoot to kill" policy for those who try to escape. Nury Turkel is a co-founder and chair of the Uyghur Human Rights Project, a commissioner for the United States Commission on International Religious Freedom, and a senior fellow at the Hudson Institute. He's just published No Escape: The True Story of China's Genocide of the Uyghurs. He tells Kathryn how the unfolding Uyghur crisis is turning into the greatest human rights crisis of the twenty-first century.
