Turkey admitted on August 1, 2016 there may have been some "unfair" treatment in its post-coup crackdown as it voiced anger at Germany for barring President Recep Tayyip Erdogan from addressing a rally in Cologne. Prime Minister Binali Yildirim told a top-ranking US general that his government remained committed to principles of law in its fight against coup plotters and called for Washington to extradite US-based preacher Fethullan Gulen "as soon as possible". During their meeting, the Turkish premier also told Dunford that the Turkish armed forces were fulfilling its duties "at full capacity" after the reshuffling in the wake of the coup attempt and said that cooperation continued "uninterrupted" with the US and other allies in the fight against terrorist groups including the Islamic State (IS) jihadists. / AFP PHOTO / TURKISH PRIME MINISTRE PRESS OFFICE / HAKAN GOKTEPEHAKAN GOKTEPE/AFP/Getty Images
