China's secret internment camps

China has been quietly detaining its population of Uighurs, the country’s Muslim minority, in internment camps. First-hand accounts from inside the camps paint a brutal picture of torture and political indoctrination. At first, China denied the existence of these camps and tried to cover them up. But as a network of academics and activists uncovered evidence of the camps' locations, and the reality of what’s going on inside, China changed its story.
