International Security and Terrorism analyses contemporary issues in international orders. This book assesses the terrorist attacks which were organised in African, Asian, European and Middle Eastern countries in detail. Therefore, it provides a comprehensive understanding for academics, practitioners, researchers, students and readers who are interested in international security and terrorism. It utilises data about casualties, attack types and countries that exposed terrorism. The book critically examines terrorism, traditional counter-terrorism tactics, securitisation and the new terrorism. It focuses on religiously-motivated terrorist groups, e.g. al-Qaeda, ISIS, Boko Haram and al-Shabaab.Aytaç Kadıoğlu is an assistant professor of politics and international relations at the Middle East Institute, Sakarya University.
