THE HAGUE, Feb. 10 (Xinhua) -- Fifteen people were arrested across the Netherlands on Tuesday in a terrorism investigation, the Dutch Public Prosecution Service (OM) announced.

The suspects, aged between 16 and 53, are accused of attempting to incite others to commit terrorist crimes through social media, including disseminating Islamic State (ISIS) propaganda and participating in a terrorist organization. Four of the suspects are minors.

Police units will continue to cooperate closely in what authorities describe as a large-scale criminal investigation. Further arrests have not been ruled out.

In the 2025 Terrorism Threat Assessment released on Dec. 2025, Dutch National Coordinator for Counterterrorism and Security maintained the terrorism threat level at "substantial" which indicates that the risk of a terrorist attack remains real. Authorities warn that the primary jihadist threat to Europe continues to stem from the ISIS. The radicalization of a new generation of young people active in online jihadist networks is described as particularly worrying.

The Public Prosecution Service is the only authority in the Netherlands empowered to bring criminal suspects before the courts and is responsible for directing criminal investigations and prosecutions.
