They just said on the radio that Turkey, as a protest against the bomb attack in Ankara (which was presumably organized by the Turkish government), will not be present at the conference about the refugees organized by the European countries. This is pure political blackmail. Some days ago Russia was accused of bombing a hospital in Aleppo while Turkey was bombing civilian targets of the Kurds in Northern Syria. The UN and the US were only talking about the Russian bombings and kept silence about the Turkish bombings + military intervention. Today, Russia said ‘NO’ to a no fly zone of NATO in Syria (Turkey is a key member of NATO).
