Afghan children raped with 'impunity,' U.N. official says

(CNN) -- The young Afghan girl sits in the center of the room, weeping. Using her hand and her blue scarf to hide her face, she recounts how she was brutally raped by five gunmen.

Shaima says justice is hard to find. "These criminals are never brought to justice, because police and government authorities are either involved or they can't handle the crimes," she explains. "With criminals and warlords in the political scene, we cannot expect justice to be served."
