The speed of Afghanistan's fall to the Taliban has shocked the world – but what sort of country will it become? The BBC’s Yalda Hakim was born in Afghanistan and travelled back there in the weeks before the Taliban took control. She meets a Taliban commander from the front line promising a Sharia state, and the Afghanistan vice president who was adamant he would never surrender. Also she hears from those who are now fearing for their lives and their futures. Panorama asks what is at stake for the Afghans who are now in their first week under Taliban rule.
