He said Turkey will retaliate against any cross-border gunfire from the Kurdish YPG militia in Syria and will not remain silent in the face of activities by terrorist groups against Turkey overseas. Since then the Turkish-led forces have driven ISIS from a number of settlements in northern Syria.
In recent weeks, when the USA shot down a Syrian government war plane and an Iranian drone that were threatening US -allied Syrian fighters, the angry response from the Russians was to declare they would not use the deconfliction phone line.

Mattis is scheduled to meet his Turkish counterpart, Defense Minister Fikri Işık, in Brussels on Wednesday, where both have arrived to attend a North Atlantic Treaty Organisation summit.
