At least 537 people were detained as part of investigations into the Gülen movement over the past week, according to government data.
In a written statement on Monday, the Interior Ministry said 537 people were rounded up in operations targeting the Gülen movement between March 12-19.
Turkish government accuses the movement of masterminding the July 15, 2016 coup attempt while the latter denies involvement.
Nearly 150,000 people have been detained and 60,000 arrested over ties to the movement since the summer of 2016.
The ministry’s statement also said 2 others were detained over ties to what the government says radical leftist organizations in the past week.
