Turkish government has suspended 12,801 police officers from duty, pending a probe into their suspected links to a terrorist group which the government claims is led by US-based cleric Fethullah Gulen.

According to the Daily Sabah newspaper which quoted a press statement by the Turkish security general directorate, “of those suspended, 2,523 were police chiefs.”

Thousands of military and police officers, judges and educators have been suspended or laid off based on the same claim in the aftermath if a failed coup on July 15.

The Turkish government accuses the Gulen as having masterminded the coup from abroad. Turkish authorities wan Gulen, a Muslim cleric, to be extradited from the United States on charges of terrorism.

After the Putsch, Turkish government announced a three-month state of emergency, during which it has launched a severe crackdown, especially in the country’s Kurdish majority southeastern regions.

Weeks ago, the leader of Turkey's opposition Republican People's Party (CHP) said one million people have suffered Ankara’s reckless measures after the attempted coup.

Ankara has also suspended around 100,000 civil servants and detained some 40,000 people over alleged links to the opposition cleric, Fethullah Gulen.
