According to Telegraph:
Propaganda films obtained by The Sunday Telegraph in Peshawar, the capital of North West Frontier Province, show boys of 14 or 15 recording farewell messages before climbing into vehicles filled with explosives.

One film which Pakistanis have been watching with horrified fascination shows a boy of about 15, named in the video as Arshad Ali from Swat, who attacked a polling station after the Taliban banned voting last year.

Sitting with an AK-47 cradled in his lap and fiddling with prayer beads, he stares into the camera. Speaking calmly, he said that the people of Swat were living in evil times and that sacrifice was called for.

"Some hypocrites say that we are doing this for money - or because of brainwashing - but we are told by Allah to target these pagans," he said, in a reference to government claims that the families of suicide bombers were paid after the attacks.

He said: "I invite my fellows to sacrifice themselves".
