The deputy prime minister stressed that Turkey had already sent all the evidences confirming that Gulen had been the organizer of failed coup attempt and wanted his immediate extradition.
"We always told our American colleagues and friends in all our conversations with them that due to our friendship with the US, the US should extradite this leader", Kurtulmus added.
A coup attempt, which mainly involved members of the army, took place across the country on July 15, 2016. Most of the struggle happened in the capital Ankara and in Istanbul. More than 240 Turkish citizens were killed and over 2,000 wounded during the unsuccessful military takeover.
The Turkish government has accused Fethullah Gulen, an Islamic preacher living in the United States, of involvement in the coup and demanded his extradition to Turkey. More than 50,000 people were arrested and 100,000 dismissed or suspended from their jobs within the post-coup crackdown inside Turkey.
