Assignment 7.15pm BBC2
An Islamic student army, the Taliban, has seized control of the Afghan capital Kabul. So strict is their regime that they impose a curfew at night, young women are forced to wear a veil and denied the right to an education, and musicians have taken to burying their instruments for fear that their playing might be deemed "unislamic" and invite punishment.
Tonight's Assignment penetrates a Taliban training school in northern Pakistan, where passionate young fundamentalists are prepared to go to the Afghan frontline. But their sway over the people of Afghanistan is not complete. Resistance troops are already preparing to push the Taliban out of the country, setting the scene for a bloody religious war.
