North Korea 'continues to invest' in Nazi-style prison camps
Newly-released satellite images show that North Korea's prison camp system, where detainees are subjected to forced labor, torture, starvation, rape and death, may be expanding.
Up to 120,000 men, women and children are imprisoned in the gulags, known as "kwanliso" in Korean, according to the United Nations.
Pyongyang officially denies that the camps exist, but multiple human rights groups have documented their ongoing operation via survivor testimony and satellite imagery.
