ANKARA, Jan. 3 (Xinhua) -- A delegation from the United States arrived in Turkey's capital Ankara on Thursday to discuss the probe into Fethullah Gulen, the leader of the Gulenist network.
During the two-day visit, U.S. officials, including FBI officials, are expected to hold talks with Turkish counterparts as the two sides share info about the U.S.-based probe.
It is the sixth time that Turkish authorities have met U.S. officials to discuss the extradition of Gulen, state-run Anadolu Agency reported.
Fethullah Gulen, the U.S.-based preacher, is accused by Ankara of orchestrating a failed coup attempt on July 15, 2016.
The Turkish government declared a state of emergency and launched a massive crackdown on Gulen's supporters in the aftermath of the coup attempt.
Local broadcaster CNN Turk reported Thursday that the U.S. delegation will also interrogate Kemal Batmaz, one of the key suspects linked with the coup attempt, charged as the "civilian imam."
Turkish Justice Ministry has sent several files to Washington to beef up its evidences in demanding the extradition of the Islamic cleric.
Gulen has lived in self-imposed exile in the U.S. state of Pennsylvania since 1999.
