At least three people were arrested in northwestern Sakarya province on Friday over suspected links to Daesh terrorist organization, according to the local police.
The suspects were arrested during an anti-terror operation conducted by Sakarya police.
Turkish security forces have been involved in a long-running campaign to thwart Daesh attacks.
More than 300 people have lost their lives in Daesh-claimed attacks in Turkey, where the terror organization has targeted civilians in suicide bomb, rocket and gun attacks.
