HATAY, TURKEY - OCTOBER 10: Turkish Army's armored vehicles head to the Turkey's Syria border due to ongoing deployment to Idlib's de-conflict zone in Hatay, Turkey on October 10, 2017. During a meeting in Kazakh capital Astana on May 4, the guarantor countries -- Russia, Turkey, and Iran -- signed a deal to establish de-escalation zones in Syria, which included Idlib in northwestern Syria, on the Turkish border. After intensive negotiations between Turkey, which backs the Syrian opposition, and the guarantor of the regime, Russia, the deal came to the implementation phase.
