Taliban kids

The boy with the knife looks barely 12. In a high-pitched voice, he denounces the bound, blindfolded man before him as an American spy. Then he hacks off the captive's head to cries of "God is great!" and hoists it in triumph by the hair.

A video circulating in Pakistan records the grisly death of Ghulam Nabi, a Pakistani militant accused of betraying a top Taliban official who was killed in a December airstrike in Afghanistan.

An Associated Press reporter confirmed Nabi's identity by visiting his family in Kili Faqiran, their remote village in southwestern Pakistan.

The video, which was obtained by AP Television News in the border city of Peshawar on Tuesday, appears authentic and is unprecedented in jihadist propaganda because of the youth of the executioner.
