The Committee for Human Rights in North Korea (HRNK), a non-governmental organization based in Washington, D.C., has launched a report entitled North Korea: Imagery Analysis of Kyo-hwa-so No. 12, Jŏngŏ-ri – Update 3. The report methodology comprises satellite imagery analysis and former prisoner testimony. This kyo-hwa-so detention facility was first featured in the September 2015 report The Hidden Gulag IV: Gender Repression and Prisoner Disappearances by David Hawk. HRNK released two subsequent satellite imagery reports in 2016, including a September 16 rapid assessment of flood damage at the detention center, in the aftermath of Typhoon Lionrock.
