Foreign Terrorist Fighters Knowledge Hub

The Foreign Terrorist Fighters (FTF) Knowledge Hub is a trusted source for quantitative and qualitative data on FTFs who travelled to Syria and Iraq in support of terrorist or violent extremist groups, and government responses to the FTF challenge. It is a valuable resource for policymakers, researchers, and media. Access the FTF Knowledge Hub here.

    The Knowledge Hub contains individual country pages where visitors can find country-specific FTF-related data. Additionally, it contains a policy matrix containing detailed information on national prevention policies, administrative measures, criminal proceedings, surveillance measures, and rehabilitation and reintegration measure. The Hub also showcases the legal framework governing these responses, relevant international standards and guidance concerning FTFs. A separate library provides relevant academic research and policy briefs.

    The Knowledge Hub was created to:

    • Provide insight and better understanding of the FTF phenomenon;
    • Facilitate the exchange and analysis of data and information to identify the ongoing trends and dynamics within the FTF phenomenon (offering an overall overview of FTFs globally, including women, children returnees, etc.); 
    • Inspire the development of rule of law-compliant FTF policies; and
    • Catalyse further implementation of GCTF's The Hague - Marrakech Memorandum.

    ICCT developed the Knowledge Hub in partnership with the T.M.C. Asser Instituut, with contributions from the United States and Jordan as co-chairs of the Global Counterterrorism Forum (GCTF) FTF Working Group. It builds on the previous FTF Knowledge Hub hosted by and developed under the auspices of the GCTF and is inspired by GCTF Framework Documents. However, in its new form, the FTF Knowledge Hub is completely independent from its predecessor, and information has been gathered by researchers from the Asser Institute and the ICCT via credible open-source research. This information does not in any way bind the GCTF and its Members, the Asser Institute or the ICCT.

    As an open-source product, Foreign Terrorist Fighters Knowledge Hub welcomes the contribution of country-specific data, relevant research and literature on FTFs. We also welcome information and data on preventive, administrative, criminal and surveillance measures, as well as rehabilitation and reintegration measures. To submit information, please fill out our questionnaire, and send it to

    Please note that the researchers maintaining this website reserve the right to reject submissions and that published data will become publicly available. Information on the Knowledge Hub will be reviewed and updated on a regular basis.
