LUXEMBOURG (AP) -- The Obama administration would entertain an extradition request for the U.S.-based cleric that Turkey's president is blaming for a failed coup attempt, U.S. Secretary of State John Kerry said Saturday.
In a televised speech, Turkish President Recep Tayyip Erdogan said the United States should extradite Fethullah Gulen. Erdogan said Turkey had never turned back any extradition request for "terrorists" by the United States and stressed Turkey's joint role with the U.S. in fighting terrorism. "I say if we are strategic partners then you should bring about our request," he said.
Visiting Luxembourg, Kerry said Turkey would have to prove the wrongdoing of Gulen, who left Turkey in 1999.
Gulen has harshly condemned the attempted coup attempt by military officers that resulted in a night of explosions, air battles and gunfire that left dozens dead. But Erdogan's government is blaming the chaos on the cleric, who lives in exile in Pennsylvania and promotes a philosophy that blends a mystical form of Islam with staunch advocacy of democracy, education, science and interfaith dialogue.
Erdogan has long accused Gulen, a former ally, of trying to overthrow the government. Washington has never found any evidence particularly compelling previously.
"We fully anticipate that there will be questions raised about Mr. Gulen," Kerry told reporters. "And obviously we would invite the government of Turkey, as we always do, to present us with any legitimate evidence that withstands scrutiny. And the United States will accept that and look at it and make judgments about it appropriately."
A Turkish official, speaking on condition of anonymity in line with government regulations, said Turkey "has been preparing a formal application with detailed information about Gulen's involvement in illegal activities. After last night, we have one more thing to add to an already extensive list."
President Barack Obama urged all sides in Turkey to support the democratically elected government in Turkey, a key NATO ally.
In a statement issued after a meeting with his national security advisers, Obama also urged those in Turkey to show restraint and avoid violence or bloodshed.
Gulen is understood to maintain significant support among some members of the military and mid-level bureaucrats. His movement called Hizmet includes think tanks, schools and various media enterprises. Gulen and Erdogan only became estranged in recent years.
Gulen said he condemned, "in the strongest terms, the attempted military coup in Turkey" and sharply rejected any responsibility or knowledge of who might be involved. At a news briefing in Saylorsburg, Pa., Gulen noted that he's been away from Turkey for more than 15 years and wouldn't have returned even if the coup succeeded due to greater freedoms in the U.S.
"In brief, I don't even know who my followers are," the frail-looking cleric said through an interpreter. "You can think about many motivations of people who staged this coup."
Reiterating American support for Erdogan's government, Kerry said the U.S. opposed any attempt to overthrow a democratically elected leader. He said a change of government should only come through a legal, constitutional process.
Kerry also said that U.S. military cooperation with its NATO ally has been unaffected by the turmoil. Turkey plays a key role in U.S.-led efforts against the Islamic State in Syria and Iraq.
"All of that continues as before," Kerry said.
He said the U.S. had no prior indication of the coup attempt, which came as Erdogan was on vacation.
It appears not to have been backed by the most senior ranks of the military, and Turkey's main opposition parties quickly condemned the attempted overthrow of the government. Prime Minister Benali Yildirim said 161 people were killed and 1,440 wounded in the overnight violence. He said 2,839 plotters were detained.
"If you're planning a coup you don't exactly advertise to your partners in NATO," Kerry said. "So it surprised everyone. It does not appear to be a very brilliantly planned or executed event."
