Turkish authorities ordered the dismissal of more than 18,500 state employees including police officers, soldiers and academics, in a decree published on Sunday.
The Official Gazette said 18,632 people had been sacked including 8,998 police officers in the emergency decree over suspected links to terror organisations and groups that "act against national security".
Some 3,077 army soldiers were also dismissed as well as 1,949 air force personnel and 1,126 from the naval forces.
Another 1,052 civil servants from the justice ministry and linked institutions have been fired as well as 649 from the gendarmerie and 192 from the coast guard.
Authorities also sacked 199 academics, according to the new decree, while 148 state employees from the military and ministries were reinstated.
Turkey has been under a state of emergency since the July 2016 attempted overthrow of President Recep Tayyip Erdogan.
