On this episode of Assignment Asia, our correspondent Danial Khan investigates the roots of the Pakistani madrassa, the core of religious education for many Pakistanis. Over the last 15 years or so, these schools have come under intense scrutiny for providing an atmosphere that fosters religious extremism – seen today in a post-9/11 world, with the rise of groups like ISIL and the Taliban. Danial takes us through the history of the madrassa and talks to experts to give us a more in-depth picture of this traditional educational institution. (Asia Asignment)
