Siyamend Kaçmaz / St. Petersburg, Aug 10 () - Turkish President Recep Tayyip Erdoğan has said the followers of Fethullah Gülen, the U.S.-based Islamic preacher who is blamed for organizing the bloody July 15 coup attempt, had also aimed at breaking the Ankara-Moscow relations. “The heinous attack on July 15 has been returned by our nation. It is clearly understood that FETÖ has aimed at the relation between our countries” Erdoğan said while speaking at a Russian-Turkish business representatives meeting in St Petersburg on Tuesday on the sidelines of the historic meetings between the leaders to put an end to a row and normalize ties. Turkish and Russian relations were frozen, with Moscow imposing harsh sanctions on Ankara after a Turkish jet downed a Russian fighter jet in November last year for violating the Turkish air space. A letter by Erdoğan to Putin in June was a milestone for mending the ties and on Tuesday, both parties pledged to put everything back on track.
