Turkish law enforcement officials are basing the 14 December crackdown throughout Turkey on a former police operation allegedly carried out by members of the Gülen movement against a rival Islamist movement.

Since the rift between the Turkish government and its ally-turned-nemesis Fethullah Gülen, a US based Islamic scholar, pro-government media had been accusing the Gülen movement of “abusing” Islam. Similarly, pro-Gülen media has been slamming the government for acting “un-Islamically,” a term that the movement has also used against rival communities.

Security sources speaking to daily Hürriyet explained the chronology of the case that is the focal point of the current crackdown, which has seen the arrests of dozens of people so far, including police chiefs and media figures.
