Via porn, gore and ultra-violence, extremist groups are sinking hooks online into the very young

Across Europe and further afield, counterterrorism agencies are grappling with a new generation of young people who are being radicalized online and consuming ultraviolent content produced by extremist groups and their supporters. Numbers of terror investigations involving children and teenagers are surging. And intelligence agencies are warning that radicalized minors can pose as much of a terror threat as adults. In France, the national anti-terrorism prosecutor says extremist propaganda is deliberately targeting young people. One case involved a boy aged just 12, who accumulated a vast library of decapitation and torture videos and how-to bomb-making guides.
