Despite Turkey's claims US should create a buffer zone on the Turkish border with Syria, Washington isn't actively considering that issue.
Russian Foreign Ministry spokesman Alexander Lukashevich said Thursday the decision on a buffer zone on the border with Syria may only be made by the United Nations Security Council.
The speaker reminded what happened in Iraq, Libya when important decisions were made with no resolution from the United Nations Security Council.
The diplomat also said decisions made by separate states or coalitions on establishment of buffer zones are illegitimate.
NATO's new Secretary General Jens Stoltenberg on Thursday met Turkey's Foreign Minister Mevlut Cavusoglu and discussed prospects for creating a no-fly and a buffer zone in Syria.
NATO secretary general also stated that the alliance will continue protecting Turkey form threats coming from the Islamic State organization.
Stoltenberg reminded about the deployment of Patriot missile defense systems near the border between Turkey and Syria. He said the systems will be used in defending Turkey's southern border if case of necessity.
According to Russian Foreign Ministry spokesman Alexander Lukashevich, Islamic State (IS) militants seized 70 villages in the vicinity of the city of Kobani.
