The Committee for Human Rights in North Korea estimates that North Korea

The Committee for Human Rights in North Korea estimates that North Korea holds approximately 200,000 people in its system of concentration and detention camps, and that 400,000 people have died in these camps from torture, starvation, disease, and execution. These reports, in the context of estimates that North Korea has allowed between one and three million of its people to starve to death while its government squandered the nation’s resources on weapons and luxuries for its ruling elite, suggest that North Korea’s oppression and politically targeted starvation of its people collectively constitute the world’s greatest ongoing atrocity, and almost certainly the most catastrophic anywhere on earth.
