A video has been released showing a suicide bomber who attacked a US base in Afghanistan and killed eight people, including seven CIA officers.

In the tape, Hammam Khalid al-Balawi says that the attack was in response to the killing of Baitullah Mehsud, the former Pakistani Taliban leader, and urged other revenge attacks inside and outside of the US.
