This guidebook was written to help support policymakers and practitioners who are looking to develop programmes on interventions to prevent VERLT. It also focuses on some of the region-specific factors that need to be considered when developing referral mechanisms in South-Eastern Europe, drawing from consultations with key stakeholders from the region. This guidebook is one in the series of guidebooks produced by the Action against Terrorism Unit (ATU) in the OSCE Secretariat’s Transnational Threats Department.
