Samenvatting

Jihadist networks have become a serious threat to Europe’s internal security and are therefore a policy priority. But what do we know about these networks and how should we counter them? This study focuses on the modus operandi of jihadist networks between 2000 and 2013 and gives an empirical insight in the organizational structures, activities, and involvement mechanisms of jihadist networks in the Netherlands. The data are derived from 28 police investigations, 51 interviews with police investigators, public prosecutors, lawyers, imams, and staff members from Asylum and Detention Centers. The findings show how jihadist networks have changed over the years and how this development has affected the way jihadists operate.
