Anti-terror police have detained 233 suspected Islamic State in Iraq and the Levant (ISIL) members in 29 Turkish provinces including Konya, Van, Eskişehir, Elazığ, Kırıkkale, İstanbul, İzmir, Mersin and Hatay, the Security General Directorate announced on Wednesday.
ISIS flags and weapons were confiscated during the operations.
The Doğan news agency said the suspects were planning an attack during commemoration events of the first anniversary of a failed coup on July 15.
The detained ISIL members allegedly fought in Syria and called themselves the “annunciators,” individuals who invite others to the true path.
Twenty-five ISIL members will be deported from Turkey.
During the operations in Konya province on Wednesday, five suspected ISIL members were killed.
