Turkish Prime Minister Binali Yıldırım said on July 18 that Turkey may question its friendship with the U.S. amid calls for the extradition of U.S.-based scholar Fethullah Gülen after a failed coup attempt.

“Even questioning our friendship may be brought to the agenda here. Nonetheless, our Justice Ministry is conducting the necessary work,” Yıldırım told reporters while speaking at a press conference after a cabinet meeting in the capital Ankara.
