Tens of thousands of North Korean prisoners have "disappeared" from an enormous Gulag in a region known for food shortages, according to the Committee for Human Rights (HRNK).
The HRNK fears the prisoners may have been starved to death before it closed last year.
Camp 22 was a vast labor camp sprawled across 700 square miles. It once held around 30,000 prisoners. According to the group's report, that number has dwindled to only 3,000 in the months before it shut down.
Defectors told the group that as many as 8,000 prisoners may have been transferred to other camps, but that leaves 22,000 prisoners who may have starved to death in the Gulag.
