Twelve-year-olds are now showing up in European terrorism cases, and the people tracking these threats say the internet is the reason why.
Quick Take
- European Union counter-terrorism officials warn that jihadist groups still pose a major danger 25 years after the September 11 attacks.
- A newer threat has grown alongside it: young people, some as young as 12, getting pulled into violent extremism online.
- Europol’s 2026 terrorism report says 108 of 347 people arrested for terror offenses were minors or young people.
- Gaming platforms, social media, and encrypted apps are named as the main places where this radicalization happens.
A Warning Timed To A Grim Anniversary
Twenty-five years after Al-Qaeda’s attacks on the United States, European Union officials say the jihadist threat has not gone away. Euronews reported that jihadist groups still pose a major security risk across Europe, with 45 terrorist attacks recorded last year alone.
But officials now point to a second, newer danger growing inside that same threat picture, one driven largely by teenagers online.
European Union Counter-Terrorism Coordinator Bartjan Wegter told Euronews that children as young as 12 are being targeted for radicalization.
He said Europe’s security services are now handling cases involving kids barely old enough for middle school, a shift that has alarmed agencies built to track adult terror cells, not classrooms full of children.
What The Numbers Actually Show
Europol’s newest terrorism report backs up the warning with hard figures. Of 347 people arrested on terrorism charges, 108 were minors or young people, a striking share of the total.
Europol’s own summary calls the involvement of young people one of the major developments shaping the current terrorism landscape, cutting across every ideology tracked in the report, not just jihadist extremism.
This is not a brand-new discovery. Earlier Europol reports already flagged the trend. The 2025 report found 114 of 449 arrested suspects were young people tied to jihadist terrorism, the largest single group, ahead of right-wing extremism.
The 2024 report noted young adults and minors were involved in planning attacks and producing propaganda that same year. The pattern has been building for several years running.
A quarter of a century after the Al-Qaeda attacks on the United States, jihadist groups still pose a major threat to security in Europe, but a new menace has surfaced that is driven mostly by young people online and the authorities are worried.

Where The Radicalization Actually Happens
Europol says the online world gave extremist groups fast, wide, and often hidden access to vulnerable young people. That access sped up exposure to violent content and made it easier for radicalized individuals to coordinate with each other across borders.
Officials specifically name gaming communities and violent digital subcultures as places where multiple extremist ideologies now blend together and target the same isolated kids.
Europol has already tried to fight back on this front. The agency coordinated a Referral Action Day focused on minors, flagging more than 2,000 links pointing to jihadist and right-wing extremist propaganda aimed squarely at young users.
Mental health struggles, social isolation, and heavy digital dependency are listed as key factors that make young people easier targets for recruiters.
A Threat That Refuses To Fade
None of this erases the original threat that defined the last 25 years. Europol still describes an extremist minority operating out of the Middle East, working alongside people born and raised inside the European Union who get radicalized fast and have proven willing to act. The youth trend runs alongside that older threat, not in place of it.
EU warns of new online terror threat from youth seeking violent thrills
European Union counter-terrorism officials are concerned about a new wave of "nihilistic violent extremism" driven by young people online, distinct from traditional jihadist threats. These groups, often…

For American parents watching this unfold, the lesson lands close to home. Extremist recruiters go where kids already are, whether that’s a gaming lobby, a group chat, or a video feed.
Europe’s counter-terrorism chiefs are sounding the alarm now because the recruitment window has quietly dropped to age 12, and no border keeps that kind of content out.
