Turkish security forces have detained six Iraqi nationals in the northern province of Çankırı for their alleged links to ISIL.
The suspects were transferred to the provisional security office after a medical checkup.
Security forces have been involved in a long-running campaign to clear ISIL militants from Turkey.
More than 300 people lost their lives in ISIL-claimed attacks in Turkey, where the group has targeted civilians in suicide bomb, rocket, and gun attacks in recent years.
