ISTANBUL, Jan. 11 (Xinhua) -- Turkish prosecutors on Friday issued detention warrants for at least 102 suspects, including serving soldiers, over their alleged links to a group believed to be behind a failed coup in 2016.

Police launched simultaneous operations in 20 provinces across the country to catch a total of 52 military personnel on the orders of the Chief Public Prosecutor's Office in the southern province of Adana, according to local media the Hurriyet daily.

Among them, 42 are serving in the Turkish armed forces, while the rest are either expelled or retired, the report added.

Additionally, police are hunting for 50 suspects, including six soldiers in active service, in a separate operation ordered by the Chief Public Prosecutor's Office in Istanbul, Hurriyet said.

The suspects allegedly contacted via pay phone with the network headed by U.S.-based Turkish cleric Fethullah Gulen.

The Turkish government has been blaming Gulen and his group for the coup attempt in July 2016, in which 250 people were killed, and has been pushing for his extradition.
