Turkey has detained 6,000 people over Friday's failed coup and the number is expected to rise further, Justice Minister Bekir Bozdag has said.
The sweep has included high-ranking soldiers and 2,700 judges. More than 50 senior soldiers were detained in the western province of Denizli on Sunday.
Mr Bozdag described the arrests as a "clean-up operation".
At least 265 people were killed in clashes as the coup failed.
Turkish President Recep Tayyip Erdogan says parliament might consider a proposal to introduce the death penalty.
Mr Erdogan has accused a US-based Turkish cleric, Fethullah Gulen of being behind the plot, which Mr Gulen denies.
High-profile arrests
The arrests reportedly include Gen Erdal Ozturk, commander of the Third Army; Gen Adem Huduti, commander of the Second Army; and Akin Ozturk, the former Chief of Air Staff.
Maj Gen Ozhan Ozbakir, commander of the Denizli garrison, was among the senior military figures arrested on Sunday, Turkey's Anadolu news agency reports.
One of Turkey's most senior judges, Alparslan Altan, has also been taken into custody.
Eight Turkish soldiers who fled to Greece and claimed political asylum have appeared in court there charged with illegal entry.
Their lawyer told Greek TV they had not taken part in the coup, but had flown to Greece when they were shot at by Turkish police. Turkey is seeking their extradition.
