Map of North Korea prison camps

American TV journalists, Laura Ling and Euna Lee are kept in one of North Korea's prison camps. North Korea sentenced the two Americans to 12 years of hard labor.

The map was published by the U.S. Committee for Human Rights in North Korea via CNN's Anderson Cooper’s blog. The document shows satellite images of the camps.

I posted below a research work by David Hawk, U.S. Committee for Human Rights in North Korea entitled "The Hidden Gulag: Exposing North Korea’s Prison Camps Prisoners’ Testimonies and Satellite Photographs."
