Terrorism analyst Evan F. Kohlmann unveils a new angle to the deadly international terrorist organization and reveals the root of its terror lies in the Bosnian War. He includes recently declassified American and European intelligence reports, secret Al-Qaida records and internal documents, and interviews with notorious figures such as London-based Bin Laden sympathizer Abu Hamza Al-Masri. This is the first book to uncover the secret history of how Europe was systematically infiltrated by the ranks of the most dangerous terrorist organization on earth, as told by the terrorists themselves and the daring investigators who have tirelessly tracked them over the past decade.
