"In another concession to Russia, the resolution said the ceasefire will not apply to operations against the Islamic State group or al-Qaeda, along with individuals, groups, undertakings and entities associated with the terror groups."
Is this the out to keep hitting Efrin? There are no ISIS or Daesh in Efrin, but Turkey says YPG is PKK. Ironically, Turkey employs both ISIS and al Qaeda in their FSA. Fact.
Russia isn't trying to hit the Kurds, they're trying to hit the western backed Sunni orcs fighting alongside ISIS in E. Ghouta.
I doubt anyone at the UN is giving Afrin a second thought.
