Police launched simultaneous operations in 38 provinces across Turkey in a probe led by state prosecutors in the central Turkish province of Konya, the broadcaster said.
It said the suspects were targeted based on statements by soldiers previously detained over ties to the cleric Fethullah Gulen and were believed to have been responsible for recruiting students for Gulen’s movement.
The UN human rights office said earlier this month Turkey has detained 160,000 people and dismissed nearly the same number of civil servants since the failed coup in July 2016, which Ankara blames on Gulen. He denies any involvement.
Among those detained, more than 50,000 have been formally charged and kept in jail during trial.
Turkey’s western allies have criticized the crackdown.Critics of President Tayyip Erdogan accuse him of using the failed putsch as a pretext to quash dissent. Turkey says the measures are necessary to combat threats to national security.
