Leaked records expose China's Xinjiang camps

Newly leaked Chinese records have revealed for the first time the system by which hundreds of thousands of Uyghurs have been monitored and detained in heavily fortified internment centers across Xinjiang. According to the leak, Chinese citizens can be sent to the camps for reasons such as growing beards, owning passports, or having too many children and their release may depend on how well their family behaves.
