Sarajevo Summit Confronts the Rapid Digital Evolution of Radicalisation in the Western Balkans
The city of Sarajevo became the focal point of regional security discourse on 11–12 September 2025, as it hosted the Ad Hoc Meeting on Online Radicalisation and Disinformation in the Western Balkans. This high-level gathering, the second of its kind orchestrated by the EU Knowledge Hub on Prevention of Radicalisation (EUKH), served as a critical platform for policymakers, researchers, law enforcement, and civil society representatives. As the Western Balkans navigates a period of heightened geopolitical sensitivity, the meeting was tasked with dissecting the complex intersection of digital threats that are currently testing the region’s stability. Participants were clear in their assessment: the digital frontier has become the primary theater for extremist actors aiming to exploit local vulnerabilities.
Discussions throughout the two-day summit highlighted a sobering evolution in how extremist ideologies infiltrate the social fabric of the Balkans. Attendees noted that the regional landscape is increasingly characterized by fragile interethnic cooperation, which is compounded by persistent malign foreign influences and an underlying lack of institutional resilience. By mapping these systemic weaknesses, the summit addressed how disinformation campaigns are no longer merely accidental byproducts of social media, but rather intentional, strategic tools designed to deepen communal fractures. The consensus among the experts was that the current digital ecosystem facilitates a cycle of radicalisation that is faster, more pervasive, and significantly more difficult for state authorities to interrupt than traditional models of influence.
A central pillar of the Sarajevo meeting was the recognition of a definitive paradigm shift away from traditional radicalisation hubs. In the past, extremist recruitment efforts were largely anchored in physical spaces—such as specific prayer houses, correctional facilities, and insular community gatherings—where authorities had established monitoring protocols. However, the EUKH report presented at the event confirms that these activities have largely migrated into fully digital environments. The transition to the online space has removed geographical boundaries, allowing radical elements to operate in transnational, informal networks that bypass the surveillance tools and mediation strategies that previously defined counter-radicalisation efforts.
The meeting shed light on the sophisticated methodologies employed by extremist groups to circumvent detection. Participants observed that perpetrators are increasingly exploiting the architecture of modern digital platforms, leveraging social media algorithms to create “echo chambers” that insulate potential recruits from opposing views. Beyond mainstream platforms, there has been a strategic pivot toward encrypted messaging apps and niche gaming communities. These platforms provide a shroud of privacy that allows recruiters to disseminate extremist content, coordinate activities, and groom individuals with minimal interference from content moderation algorithms or cybersecurity interventions.
The hybridisation of content emerged as a particularly concerning trend during the sessions. Experts warned that the lines between standard political discourse and genuine extremist propaganda are becoming increasingly blurred. By blending authentic local grievances with hyper-nationalist or ideological rhetoric, recruiters are able to broaden their reach and normalize radical narratives among wider demographics. Because this content often circulates within transnational networks, it poses a direct challenge to national authorities, who struggle to frame legal and technical responses in an online landscape that often rewards sensationalism and divisive content through the mechanics of viral engagement.
As the meeting concluded, the overarching message was one of urgent, collaborative action. The participants acknowledged that traditional, state-centric approaches to prevention are no longer sufficient to secure the region. Addressing these digital threats requires a multifaceted response that includes enhanced cooperation between Balkan states, deeper partnerships with tech platforms, and a more robust digital literacy curriculum for the public. By establishing this dialogue, the Sarajevo convening served as a necessary catalyst for developing a modern, resilient framework capable of countering the sophisticated dynamics of online radicalisation in an increasingly connected, yet fragmented, region.
