Dutch authorities have arrested 15 individuals accused of disseminating Daesh (ISIS) propaganda on TikTok, in a nationwide operation targeting online terrorist content. The suspects, ranging in age from 16 to 53, are alleged to have shared extremist material designed to “incite others to commit terrorist crimes,” according to a statement released Tuesday.
The operation follows a months-long investigation that began in August 2025, with police executing coordinated raids across the Netherlands. According to the Dutch public prosecution office (OM), the content in question included Daesh propaganda videos translated with Dutch subtitles that explicitly encouraged viewers to “join the fight.”
Officials expressed particular concern over the reach of these materials, noting that some posts had garnered more than 100,000 views on the popular social media platform. This level of engagement suggests the potential for widespread radicalization efforts targeting Dutch-speaking audiences.
“The 15 are suspected of incitement to commit a terrorist offence, disseminating Daesh propaganda, and/or participating in a terrorist organisation,” the OM stated in its official release. These charges carry significant penalties under Dutch counter-terrorism laws.
The case highlights the ongoing challenges European security services face in combating online extremism. TikTok, with its algorithm-driven content delivery and predominantly young user base, has become an increasingly concerning vector for extremist messaging. The platform’s short-form video format allows for quick, emotionally charged content that can be easily distributed before content moderation systems identify and remove it.
The Netherlands has maintained vigilance against terrorist threats following several incidents across Europe in recent years. Dutch counter-terrorism officials have repeatedly warned about the dual threats of both jihadist and far-right extremism finding audiences online.
Security experts note that terrorist organizations have evolved their recruitment strategies to leverage popular social media platforms rather than relying solely on encrypted messaging apps or dark web forums. This shift allows them to cast a wider net for potential recruits, particularly targeting vulnerable young people.
“What makes this case particularly concerning is the age range of the suspects,” said terrorism analyst Pieter van Ostaeyen, who was not directly involved in the investigation. “Having both teenagers and middle-aged suspects suggests Daesh propaganda is finding resonance across demographic groups in the Netherlands.”
Dutch authorities have not yet released details about the specific content of the videos or whether the suspects were coordinating their efforts. It remains unclear if the individuals were directly connected to Daesh or were acting as sympathizers without formal ties to the organization.
The arrests come amid heightened concerns across Europe about the potential for terrorist violence following recent global conflicts. Security services across the continent have reported increased online activity from various extremist groups attempting to exploit international tensions.
TikTok has not yet commented specifically on this case, though the platform has previously stated its commitment to removing terrorist content. The company has faced criticism from security experts who argue that its content moderation systems fail to adequately address non-English extremist materials.
The Dutch prosecution office indicated that investigations are ongoing, suggesting more arrests could follow. Authorities are examining electronic devices seized during the raids for evidence of broader networks or additional propaganda materials.
The case represents one of the largest coordinated actions against online terrorist propaganda in the Netherlands in recent years. It underscores the continuing challenge for both governments and tech platforms in preventing extremist organizations from exploiting social media to spread their ideology and recruit new members.
