Around 6,000 people have been arrested since a failed coup attempt was crushed in Turkey, Justice Minister Bekir Bozdag says, according to the state-run Anadolu news agency.
Bozdag hasn't provided a further break-down of who is in custody.
"Right now, the cleansing is continuing," he said, adding that related judicial processes were also ongoing.
President Recep Tayyip Erdogan blames Fethullah Gulen, a US-based Turkish-born preacher and one-time ally turned rival accused of running a "parallel state." Gulen denies this.
Arrests so far have focused on the armed forces and the judiciary.
