A Decade After Brussels Attacks: EU Terror Chief Highlights Shift to Online Threats

In Europe
March 23, 2026

In the wake of the tenth anniversary of the Brussels terrorist attacks, the European Union’s counter-terrorism chief has underscored a significant evolution in the nature of threats facing the region. The 2016 attacks, which tragically claimed the lives of 32 individuals and injured hundreds more, exposed critical vulnerabilities within the EU’s borderless travel framework. However, in today’s digital age, the focus has shifted dramatically from physical attacks to online radicalization and cyber threats.

EU Counter-Terrorism Coordinator, Gilles de Kerchove, emphasized that as security measures at physical borders have tightened, extremist groups have increasingly turned to the internet as a platform for recruitment and radicalization. “The internet has become a battleground for ideologies, where groups can spread their message to a global audience with unprecedented ease,” he stated during a recent press briefing.

De Kerchove noted that the rise of social media and encrypted communication platforms has made it more challenging for law enforcement agencies to monitor and counteract these threats. He urged member states to collaborate more effectively in sharing intelligence and developing strategies to combat online radicalization.

Furthermore, the EU has initiated several programs aimed at enhancing cybersecurity and countering online extremism. These initiatives focus on not only disrupting the digital presence of terrorist organizations but also on promoting counter-narratives and supporting community resilience against radicalization.

As the anniversary serves as a somber reminder of the past, it also highlights the necessity for the EU to adapt its security strategies to the changing landscape of terrorism. With the threat now predominantly online, officials stress the importance of innovative approaches to ensure the safety and security of citizens across Europe.
