Please Read Huge Massacre in North Korea's Killing Fields, by Jeremy Reynalds, at Religion Today.
"The disappearance of at least some 20,000 prisoners of conscience from North Korea's Camp 22 -- a massive concentration camp -- is a huge massacre of an already brutalized population. The camp was geographically larger than Los Angeles and thought to have once held between 30,000 to 50,000 prisoners.
"According to a story by Robert Park published in Forbes and the Chicago Tribune, satellite photographs indicate that guard posts, interrogation and detention facilities at the camp had been razed last year. By that time, those accused and exploited had been reduced to about 3,000.
"While an estimated 7,000-8,000 prisoners are believed by some observers to have been taken away at night via train to similar slave labor/death camps No. 16 (located in a secluded mountain area in Hwasong County) and No. 25 (near the city of Chongjin), the rest remain unaccounted for.
"In an August report, David Hawk of the Washington, D.C.-based Committee for Human Rights in North Korea (HRNK) commented on Camp 22's rapid depopulation: “If even remotely accurate, this is an atrocity requiring much closer investigation.”
"Park said North Korea's reasons for shuttering this camp should not surprise anyone.
"On the basis of testimony from former camp guards Ahn Myong-chol and Kwon Hyuk, worldwide attention has been focused on the horrors which took place daily at Camp 22; a literal killing field.
"Park said perhaps most shocking amid the revelations of the DPRK's inhumanity provided by Ahn and Kwon's lengthy and detailed confessions, are claims of human vivisection, and chemical and biological weapon experiments on prisoners. They includes the murdering of whole families in gas chambers.
"The 2004 BBC This World documentary “Access to Evil” showed eyewitness testimonies and hard evidence (such as DPRK documents) suggesting that widespread human experimentation was taking place inside North Korea's prison camps..."
