Turkey wants the U.S. to extradite him, but President Barack Obama repeated Washington's stance on Friday, saying Ankara must first provide clear evidence of his involvement.
The justice minister said Turkey would not bow to pressure from the European Union to rule out restoring the death penalty to execute the plotters. Although Turkey has been accepted as a member of the North Atlantic Treaty Organization (NATO) it was mainly a response from the organization to fight back the Soviet Union during the cold war period, not because there is an actual harmony between Turkish beliefs and views and those of the Western countries.

"We condemn this coup and we are clear about our desire to see democracy sustained and flourish in Turkey".
We, Turks, were proud of saying that the era of military coup in Turkey was definitely over and belonged to history.
The presidential guard numbers up to 2,500 soldiers but at least 283 were detained after the uprising.
"Stop standing up for savages who run over citizens with tanks, who strafe people from land and the air", Yildirim said.
Some Turks, possibly influenced by traditional mistrust of USA policy in the region, have speculated that the United States is protecting Gulen and knew about the plot to overthrow the Turkish government.
Meanwhile, US Treasury Secretary Jack Lew said the United States strongly supported the Turkish Government and urged it to investigate the failed coup in a way that reinforced public confidence in democratic institutions and promotes economic stability.
"And I said that to President Erdogan".
Erdogan told France 24 in an interview broadcast Saturday that Turkey has no choice but to impose stringent security measures in the wake of the attempted coup that killed about 290 people and was put down by loyalist forces and protesters.
Within few days Erdogan will also be submitting an extradition request for Fethullah Gulen to the US.
"Everyone should stand strong", Gulen said.
Serdar Kilic, the Turkish ambassador to the United States, told a news conference on Friday that his country had submitted the "necessary documentation" for Gulen's extradition.
In his decree, Erdogan extended to a maximum of 30 days from four days the period in which some suspects can be detained.
Additionally, civil servants can only travel overseas if they have written approval from their supervisors, the Anadolu agency reported.
Erdogan announced the state of emergency - Turkey's first since 2002 - following a lengthy meeting with his national security team on Wednesday.
Tens of thousands of people have been detained, sacked or suspended since the failed coup.
Following the attempted coup the base, which is used by the USA military as well as the German Bundeswehr, had temporarily been cut off from electricity.
People have continued to celebrate the crushing of the coup since the weekend. He is the first reported detained from Gulen's family. An official complaint was filed Thursday against the commanders by the relatives.
For some Turks, the state of emergency raised fears of a return to martial law after a 1980 military coup, or the height of a Kurdish insurgency in the 1990s when much of the largely Kurdish southeast was under a state of emergency.
Those freed were said to be low-ranking soldiers. Relatives said numerous teenagers thought they were going to take part in a training exercise.
