On 14 and 15 November 2023, representatives of the ministries of justice and prison administrations of Albania, Kosovo,* Montenegro, North Macedonia and Serbia visited the High Security State Prison and the Municipality Jajce Centre for Social Welfare in Bosnia and Herzegovina to exchange good practices in preparation for release and provision of post-penal support to violent extremist prisoners (VEPs) and marginalised and vulnerable prisoners at risk of radicalisation. During the visit to the High Security State Prison, the prison practitioners exchanged experiences and gained insights into the legal and institutional framework of the prison system in Bosnia and Herzegovina, the system of professional development of its staff, programmes for rehabilitation, re-socialisation and preparation of prisoners for release, while learning also about inter-agency co-operation and community-based support to and management of former VEPs and other categories of prisoners at risk of radicalisation. The participants also visited the Municipality Jajce Centre for Social Welfare and familiarised themselves with the organisational set-up and functioning of the local institutions providing post-penal and reintegration support to such former prisoners upon their return to a local community. The study visit was organised within the framework of the regional action “Enhancing co-operation in the Western Balkans in managing violent extremism in prisons and preventing further radicalisation after release” implemented under Horizontal Facility Phase III for the Western Balkans and Türkiye, co-funded by EU and the Council of Europe and implemented by the Council of Europe.   * All references to Kosovo, whether to the territory, institutions, or population, in this text shall be understood in full compliance with United National Security Council Resolution 1244 and without prejudice to the status of Kosovo
