North Korean Gas Chambers and Medical Experiments

The number of prisoners held in the North Korean gulag is not known: one estimate is 200,000, held in 12 or more centres. Camp 22 is thought to hold 50,000.

Most are imprisoned because their relatives are believed to be critical of the regime. Many are Christians, a religion believed by Kim Jong-il to be one of the greatest threats to his power. According to the dictator, not only is a suspected dissident arrested but also three generations of his family are imprisoned, to root out the bad blood and seed of dissent.

Over the past year harrowing first-hand testimonies from North Korean defectors have detailed execution and torture, and now chilling evidence has emerged that the walls of Camp 22 hide an even more evil secret: gas chambers where horrific chemical experiments are conducted on human beings.

Witnesses have described watching entire families being put in glass chambers and gassed. They are left to an agonising death while scientists take notes. The allegations offer the most shocking glimpse so far of Kim Jong-il's North Korean regime.
