Meanwhile, 32 other detainees were handed over to a repatriation centre to be deported on the grounds that they pose a threat to the country.
Authorities identified a ringleader, who allegedly organised illegal classes and preaching to recruit supporters, and found dozens of suspects linked to Yalova attack, propaganda activities, or conflict zones.
As a result, simultaneous raids at 114 addresses in Istanbul and two other provinces on December 30, 2025, led to the detention of 110 suspects.
The investigations are ongoing as part of Türkiye’s broader efforts to prevent the terrorist organisation’s recruitment, propaganda, and organisational activities following a deadly Yalova attack that killed three police officers on December 29.
Turkish security forces eliminated at least six Daesh terrorists following the Yalova attack.
