At least 12 teachers were taken into custody as part of an investigation into the Gulen movement in Turkey’s several cities.

Media said Tuesday that an Antalya prosecutor issued warrants for 15 people over their alleged ties to the movement. 12 of the suspects, who used to work as teachers before their licenses were revoked were rounded up in Antalya, Aydin, Manisa and Ordu provinces.

Turkish government accuses Gulenists of being behind the July 15, 2016 failed coup while the latter denies involvement. More than 90,000 people were put in pre-trial detention over Gulen links so far.
