Turkish police are currently conducting an operation across 15 provinces of Turkey to arrest the suspects, the sources added.
The Turkish government has said U.S.-based Fetullah Gulen had organized the July 15 coup attempt, which left 240 people martyred and nearly 2,200 injured.
Gulen, who has lived in self-imposed exile in the U.S. state of Pennsylvania since 1997, is also accused of running a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police and judiciary, forming what is commonly known as the parallel state.
