The recommendations and analysis draw on ODIHR research and on advice and input obtained from a broad range of individuals – from the OSCE, other international organizations, non-governmental organizations and academia – with recognized expertise in human rights and counter-terrorism issues. Input was gathered, in particular, at an Expert Meeting on “The implementation of legislation and policies to counter the phenomenon of foreign terrorist fighters: a human rights perspective”, held in Warsaw on 25 and 26 April 2017, and a subsequent distance peer-review with meeting participants and other key stakeholders in March and April 2018.11 The paper also builds on previous research and activities carried out by ODIHR, including an Expert Workshop on “The phenomenon of foreign terrorist fighters: a human rights perspective”, held in March 2015, and a background paper on the subject prepared for the 2015 OSCE-wide Counter-Terrorism Conference.12 The May 2018 OSCE-wide Counter-Terrorism Conference in Rome, which was dedicated to the new challenges connected to the reverse flow of FTFs, and a side event ODIHR organized at the margins of the Conference, also provided valuable input for the finalization of this document.13 11  “Human rights-based approach key to effectively countering phenomenon of foreign terrorist fighters, experts underline at ODIHR meeting”, OSCE/ODIHR, 26 April 2017, <www.osce.org/odihr/313906>. 12  “Background Paper: Countering the Incitement and Recruitment of Foreign Terrorist Fighters: The Human Dimension”, OSCE/ODIHR, 25 June 2015, <www.osce.org/odihr/166646>, (hereafter, “Background Paper: Countering the Incitement and Recruitment of Foreign Terrorist Fighters: The Human Dimension”, OSCE/ ODIHR). 13  See: Chairmanship’s Perception Paper on the 2018 OSCE-wide Counter-Terrorism Conference, op. cit., note 4. 10 Guidelines for Addressing the Threats and Challenges of “Foreign Terrorist Fighters”
