Turkey warned the Trump administration Tuesday that it will pay the price for refusing to extradite a cleric living in Pennsylvania who is thought to have played a role in a 2016 coup attempt.

“We are warning many of our friendly countries around the world and demanding the extradition of the terrorists hiding within their borders,” Recep Tayyip Erdogan said at the United Nations General Assembly in New York City. “However, some of our friendly countries are shying away from extraditing the terrorists. But the price at the end for such a failure will be quite hefty.”
