Europe Warns of Rising Youth-Driven Online Violent Extremism

European authorities have raised concerns over a growing form of violent extremism driven largely by young people through online networks, warning that digital communities are increasingly encouraging violence that later moves into the real world.

While jihadist organisations continue to pose a significant security threat across Europe, officials are now focusing on what they describe as nihilistic violent extremism. Unlike traditional extremist movements, this emerging threat is often driven less by political or religious ideology and more by a fascination with violence, notoriety and gaining status within online communities.

European Union Counter-Terrorism Coordinator Bartjan Wegter said the phenomenon is increasingly characterised by violence without a clear ideological objective. Young people, particularly boys, are being drawn into online networks where violent content is shared and encouraged, sometimes resulting in attacks offline.

Investigators from nine European countries identified around 4,340 online addresses linked to a digital community known as "The COM" during an operation conducted in June and July. However, authorities say the overall size of the network remains unclear, partly because definitions of nihilistic violent extremism differ across countries and some crimes may be classified as ordinary criminal activity rather than terrorism.

The wider terrorism threat remains significant. Europol recorded 45 terrorist attacks across 10 European Union countries last year. Nearly half of these attacks were either prevented or failed, while six people were killed. Authorities arrested 486 people suspected of links to terrorism across 21 EU countries, with jihadist networks accounting for a major share of both attacks and arrests.

Officials are particularly concerned about the involvement of minors. Around one-third of those arrested in terrorism-related cases were under the age of 18, with most being boys.

Authorities say the newer form of online-driven violence has grown over the past two to three years. Several cases involving teenagers have highlighted concerns about young people allegedly seeking attention and recognition through violent acts shared or discussed online.

According to European security officials, these cases are often connected through online communities where violence can become a form of social currency. Participants may share graphic material, discuss attacks and compete for attention or status. The absence of a clear ideological motive can make such threats especially difficult for investigators to identify.

Another major challenge is that many young suspects have no previous criminal record and may leave few warning signs outside their online activity. Much of this activity can also take place inside encrypted platforms and closed digital communities, making it harder for law enforcement agencies to detect potential threats.

European authorities are also monitoring extremist networks such as 764, which has been linked to serious allegations involving violent and sexual crimes. Officials say such groups demonstrate how online communities can connect individuals across borders and expose vulnerable users to increasingly extreme material.

The rise of artificial intelligence has added another dimension to the challenge. Europol has warned that criminals and extremist networks are using AI tools to create and distribute propaganda, manipulate images and audio, and amplify harmful content through deepfakes, memes and automated accounts.

AI-powered systems can also make it easier to spread extremist messaging and increase the reach of violent material online, raising concerns among security agencies about how quickly such content can circulate.

European officials say modern counter-terrorism investigations are increasingly centred on the digital world, with a large share of cases involving online evidence and activity. The shift has renewed debate over how law enforcement agencies should respond while balancing security concerns with privacy and digital rights.

As Europe continues to face threats from jihadist groups, the rapid growth of youth-driven online networks promoting violence has emerged as an additional security concern. Authorities now face the challenge of identifying and preventing violence that may develop in encrypted digital spaces before it moves from online communities into the real world.
