New Delhi: Hundreds of thousands of people, including children, are detained in political prison camps and other detention facilities in North Korea. North Korea's biggest camp for political prisoners, known as Kwanliso Prison Camp 16, stretches across 560 square kilometers, three times the size of Washington D.C. is thought to house 20,000 prisoners.According to Amnesty international North Korea has made the life of prisoners hell here.The rights group says it interviewed one former security official named Lee from Kwanliso last month.Lee, told Amnesty about conditions in the camp. Lee spoke about the rape and murder of female inmates at the facility,he revealed the horror of daily life for prisoners at the site .According to Lee, women were killed after being brutally raped. ‘After a night of “servicing” the officials, the women had to die because the secret could not get out. This happens at most of the political prison camps,' he said. According to Amnesty, Lee said he witnessed prison officers strangling detainees and beating them to death with wooden sticks, Lee told that inmates are forced to dig their own graves here.Here prisoners spend most of their time being forced to work in extremely dangerous conditions with inadequate food and very little sleep. Lee told that there are people also who have not committed any crime but are merely family members of those deemed guilty.They are detained as a form of collective punishment known officially in North Korea as ‘guilt-by-association'. Amnesty International has urged North Korea to close such political prisoner camps, where torture is rampant and execution commonplace.Amnesty says it has passed its latest evidence to the UN Commission of Inquiry investigating human rights abuses in North Korea.Amnesty has also released the new satellite images of the Kwanliso 15 and 16 camps which shows that North Korea's political prisons are growing.
