According to The Local news portal, citing PET, at least 125 people left to join extremist groups since 2012, but the agency’s Center for Terror Analysis (CTA) warned that the actual number could be higher.
At least half of those who left the country to fight in Syria and Iraq have returned back to Denmark, and at least 27 died in combat, according to CTA.
Jensen stated that those who return could pose a terror threat to national security.
The New York-based Soufan Group and the London-based International Center for the Study of Radicalization and Political Violence estimate that there may be as many as 5,000 Europeans fighting alongside extremist groups in Iraq and Syria.
The Islamic State militant group, operating in both of those countries, is known to recruit young people over social media.
