The Foreign Terrorist Fighters (FTF) Knowledge Hub, an open-access online resource developed by the T.M.C. Asser Instituut and the International Centre for Counter-Terrorism (ICCT), has just been updated to incorporate recent developments surrounding states’ responses to foreign terrorist fighters. In doing so, the FTF Knowledge Hub continues to be an essential resource on foreign terrorist fighters and states’ responses to them, uniquely combining quantitative and qualitative data.

Data points were updated to reflect new developments for seven states, including Algeria, Belgium, Denmark, France, Indonesia, the Netherlands and Spain. In addition, new readings have been added to the bottom of the country pages under “Additional Resources” as well as in the Library, covering topics such as the motivations and support networks behind foreign fighter mobilization, the role of socioeconomic conditions in driving recruitment, the radicalisation trajectories of Turkish women shaped by familial and societal factors, the rights of children born to FTFs, Indonesia’s diplomatic efforts to repatriate former fighters, and the EU’s approach to citizenship deprivation. With these new additions, the FTFKH aims to offer a fresh perspective on the evolving landscape of FTF mobilisation and return, providing a multidisciplinary understanding of the phenomenon across various regions and demographics.

About the FTF Knowledge Hub
The FTF Knowledge Hub is an open-access database concerning states’ responses to so-called ‘foreign terrorist fighters’, or as defined by United Nations Security Council Resolution 2178 (2014): ‘individuals who travel to a State other than their States of residence or nationality for the purpose of the perpetration, planning, or preparation of, or participation in, terrorist acts or the providing or receiving of terrorist training, including in connection with armed conflict’.

The FTF Knowledge Hub contains country-specific information on 32 different states, including FTF-related data, administrative and criminal measures, as well as rehabilitation and prevention policies, and is aimed at policy makers, practitioners, academics, journalists and students. The website provides comprehensive and detailed information specifically about FTFs who have travelled to Syria or Iraq.
