Photos Reveal Scale of Labor Camps in North Korea

Amnesty International claims the camps are expanding

(CNN) -- North Korea is showing no signs of scaling back its fearsome labor camp system, with torture, starvation, rape and death a fact of life for tens of thousand of inmates, according to human rights group Amnesty International.

The rights group released satellite images, purportedly showing evidence of expansion, including the construction of new housing blocks and production facilities, at two of the isolated regime's largest camps or "kwanliso" --15 and 16 -- used to hold political prisoners.
