(CNN) -- The scene was horrifying. Gunmen stalked through the school, shooting children as they cowered under benches and booby-trapping buildings with homemade explosives. When the siege finally ended, Pakistan was left reeling and the world wondering: Who would do such a thing? And what do they hope to achieve? The identity of the group behind the massacre at the army-run school in Peshawar is no mystery. The Pakistan Taliban -- who have long conducted an insurgency against the Pakistani government as they seek to overthrow the authorities and bring in Sharia law -- were quick to claim the terror attack. http://www.cnn.com/2014/12/16/world/asia/pakistan-taliban/index.html?hpt=hp_t1 I wasn't able to find a thread on this horrific atrocity. Did I miss it?
