A new report has detailed the command structure that two North Korean ministries use to hand down orders to those charged with carrying out mass incarcerations, torture and executions, findings that the authors say will help hold perpetrators responsible for violations of human rights.

Produced by the Database Center for North Korean Human Rights (NKDB), the report titled “Behind Closed Doors” describes how both the Ministry of State Security and the Ministry of Social Security operate through a highly centralized operational structure with the goal of “safeguarding regime security in North Korea.”
