CIA Leader's visit to show us support to Turkey over Syria and terror

American spy chief David Petraeus' visit to Turkey comes at critical time amid the huge influx into Turkey in recent days of Syrian refugees fleeing Bashar al-Assad's forces' deadly onslaught and increasing chatter over covert Iranian operations that are targeting Turkish and Western interests. The plane carrying Petraeus, the Central Intelligence Agency (CIA) director, was expected to land in Istanbul on Sunday, and he was scheduled to meet with top Turkish officials including Foreign Affairs Minister Ahmet Davutoglu, Prime Minister Recep Tayyip Erdogan and National Intelligence Organization (MİT) Undersecretary Hakan Fidan.
