The operation, which began on Tuesday, targeted 124 people accused of being followers of US-based Muslim preacher Fethullah Gulen.
Ankara accuses Gulen of being behind the abortive putsch on July 15, 2016, a charge he denies, Reuters wrote.
The suspects were said to have operated as religious guides for high-ranking military personnel, it said. The operation, which focused on the central Turkish city of Konya and was spread over 31 provinces, comes ahead of Sunday’s presidential and parliamentary elections in Turkey.
Turkey has detained 160,000 people and dismissed nearly the same number of state employees since the coup attempt, the UN human rights office said in March. Of that number, more than 50,000 have been formally charged and kept in jail during the trial.
Critics of President Recep Tayyip Erdogan say he has used the failed putsch as a pretext to quash dissent. Turkey says the measures are necessary to combat threats to national security.
Erdogan, who has dominated Turkish politics for a decade and a half, is tipped to win the presidential election, but possibly only in a runoff set for early July, opinion polls suggest.
