Amnesty International has published satellite imagery and new testimony that shed light on the horrific conditions in North Korea's network of political prison camps, which hold an estimated 200,000 people.



The images reveal the location, size and conditions inside the camps. Amnesty International spoke to a number of people, including former inmates from the political prison camp at Yodok as well as guards in other political prison camps, to obtain information about life in the camps.



According to former detainees at the political prison camp at Yodok, prisoners are forced to work in conditions approaching slavery and are frequently subjected to torture and other cruel, inhumane, and degrading treatment. All the detainees at Yodok have witnessed public executions.

"North Korea can no longer deny the undeniable. For decades the authorities have refused to admit to the existence of mass political prison camps," said Sam Zarifi, Amnesty International Asia Pacific Director.
