At least 13 teachers were detained as part of an investigation into the Gulen movement in Turkey’s southern province of Samsun, media said Friday.

Police carried out operations in several locations in the Black Sea province of Samsun and detained all the suspects.

12 of the 13 teachers were earlier dismissed from their jobs over alleged affiliation with the Gulen movement, according to media.

Meanwhile, detention warrants were issued for another 70 teachers as part of a separate investigation into the Gulenists in the capital, Ankara, state-run Anadolu news agency said the same day.

Turkish government accuses the Gülen movement of masterminding a failed putsch on July 15, 2016, and considers it a terrorist organization. The movement denies involvement in the coup and rejects terror accusations.

However, thousands of teachers as well as many from other professions have been already jailed over Gulen links.
