The Bosnian war was not only the worst in Europe since the Second World War, it also provided Osama bin Laden a foothold in Europe. Al Qaida later used this as a basis to carry out its terror attacks on Western targets, including the World Trade Centre on 9/11. This is the story of how it could happen. Ola Flyum used to work as an investigative journalist, and for NRK’s Brennpunkt. In 2001 he directed (with David Hebditch) Allies & Lies for NRK/BBC2. He directed the series Kaldt kappløp in 2010 and is the author of several books, including Rinnans testamente (2008).
