Jihadist Motivated Terrorist Attacks in Europe and North America

Attacks Tracker

2014-2020 Snapshot

The tracker is based on a database* of jihadist attacks in Europe and North America regularly updated by Program on Extremism Director Lorenzo Vidino and fellow Francesco Marone.




 *The database includes all jihadist terrorist attacks committed in North America (United States and Canada) and Europe (the 27 Member States of the European Union plus Norway, Switzerland and the United Kingdom), from the Islamic State’s proclamation of the so-called Caliphate on June 29, 2014 through November 9, 2020. For the purpose of this work, terrorism is interpreted as a deliberate act of violence against person(s), committed by one or more individuals motivated or inspired by jihadist ideology, with the intention to coerce, intimidate or convey some other message to an audience larger than the immediate victims (Lorenzo Vidino, Francesco Marone, and Eva Entenmann, Fear Thy Neighbor: Radicalization and Jihadist Attacks in the West, Report, Program on Extremism at George Washington University, June 2017). Data collection is based largely on open-source material, at times supplemented by interviews with government officials.
