ANKARA - Turkish President Tayyip Erdogan's phone call with Russian President Vladimir Putin on Wednesday was 'very productive and positive', Turkish presidential sources said, adding that a written statement would be made shortly. The phone call was arranged after Erdogan expressed regret in a letter to Putin on Monday over Turkey's downing of a Russian warplane last year, although the Kremlin later sought to dampen Turkey's hopes for a swift restoration of normal relations.
