Turkish police on Tuesday carried out simultaneous operations in 18 Turkish provinces and detained a total of 30 civilians as part of an investigation into the Gülen movement, which the government accuses of masterminding a coup attempt on July 15.

According to the Doğan news agency, the operations were conducted in line with an investigation pursued by the Batman Chief Public Prosecutor’s Office, and detainees are accused of “membership in an armed terrorist organization” and “attempting to destroy the unity of the state and nation.”
