Turkish police on Friday launched operations against suspected members of the Islamic State (IS) and detained nine suspects, local media reported.

The Istanbul Police Department’s Counter-Terrorism Unit teams raided 10 locations across the city to capture those allegedly involved in terror activities, the state-run Anadolu agency said.

Those targeted in operations were active IS terrorists in Syria and Iraq, and later entered Turkey illegally, Anadolu said, adding that eight of them were foreign nationals.

Police seized organizational documents and digital materials during the raids, the report said.

The IS has been blamed for a spate of deadly attacks in Turkey since 2015.
