Navvar Saban "Oliver" at Omran for strategic Studies Military Expert and the Information Unit manager, recent interview entitled "Syrian refugees are unwelcome in the Israeli-occupied Golan Heights" by TRTWorld via lcmporter, in the article Saban talked the following points:
1- 1. Russia is pushing for reconciliation – they want people and fighters to stay in their cities
2- 2. They don’t want to create some kind of a gap that will be filled by Iran-backed militias.
3- 3. Whenever there is a gap because of evacuation, Iran-backed militias are expert now in filling this gap.
That is a major problem for the Russians right now, especially in the south.
