Dutch police said Tuesday they had arrested 15 people suspected of spreading Islamic State propaganda on TikTok, accusing them of trying to “incite others to commit terrorist crimes.”
Police launched a nationwide swoop on the suspects, aged between 16 and 53, after an investigation launched in August 2025.
The Islamic State propaganda, with Dutch subtitles, “included calls to join the fight and glorification of martyrdom,” the public prosecution office (OM) said in a statement.
Some of the TikTok posts had been viewed more than 100,000 times, authorities added.
The 15 are suspected of “incitement to commit a terrorist offense, disseminating ISIS (Islamic State) propaganda, and/or participating in a terrorist organization,” said the OM.
Another person, described as the “main suspect in the investigation,” was already arrested in January, making 16 accused in total.
Thirteen suspects have Syrian nationality. The other three are Dutch. Four suspects are minors.
“Glorifying and disseminating propaganda significantly undermines public safety,” said the OM, recalling that publishing Islamic State propaganda was a punishable offense.
Authorities did not rule out further arrests from their investigation.
