The Seminar is organized by the Border Security and Management Unit of the Transnational Threats Department (TNTD) with the main purpose to help participating States better understand the international obligations related to border management included in UNSC Resolution 2396, to identify their technical assistance needs and challenges, and to determine ways in which the OSCE can support them in fulfilling their obligations. This year's event focuses on how to counter the risks posed by returned foreign terrorist fighters.
