New satellite images of the two most notorious North Korean prison camps show undeniable proof that the government, while persistently denying the existence of such camps, continues to upgrade the torturous facilities that appear to be ‘very much in working order.’ A new report from Amnesty International showed images of the two camps that differed from those released by the UN in 2014. In one camp there are six additional guard posts, while the old guard posts have also been maintained. These changes ‘strongly suggest that Camp 25 remains an active detention facility.’ The images also revealed ongoing agricultural activities from 2014 to 2016, with people working the land. In the past it was recorded that prisoners worked for 12 to 15 hours per day, receiving very little food. They suffered malnutrition, lost their teeth, their gums turned black and their bones became weak.
