Five suspects were arrested early Friday in a counter-terrorism operation conducted by Istanbul police, Anadolu Agency (AA) quoted security sources as saying.
The suspects were held for links to the ISIS group, said the sources, adding that the detentions took place during raids in four districts -- Silivri, Bagcilar, Maltepe and Gungoren.
The raids resulted in the capture of twelve foreign nationals who were suspected to be attempting to travel to conflict zones, the sources added. A large body of digital data and documents were seized during the operation, AA reported.
