Asia News: More than 200,000 political and religious prisoners in North Koreaby Joseph Yun Li-sun
South Korea’s National Human Rights Commission of Korea releases its findings on the matter. It is the first government agency that officially deals with the issue. Sources tell AsiaNews that many of those in detention are religious believers.
A side note: I was watching Iris with English subtitles last night, and the KBS translator wrote PRC instead of PRK. I haven't seen an instance of Corea though.
