Re-education Camp in Karakax 墨玉县教育矫治中心
In this government tender notice, there is a “educational correction center” in Karakax’s vocational school.
If we zoom in, we can see some hallmarks of reeducation camp like barbed wire fences surrounding each building.
We can also see watchtowers, like this one below.
