Uighur Intellectuals in China's Crosshairs

The United Nations estimates that the Chinese state has detained more than one million Uighurs, the ethnic Muslim minority in China, in camps. Some, have eventually been released. But notably, Communist Party officials have shown reluctance freeing Uighur intellectuals.

Activists call what's happened a cultural genocide.
