And now the Syrian Democratic Forces (SDF) own video of when the Deir ez-Zor Military Council, which is part of the SDF alliance, expanded to secure the people after al-Assad's regime forces had abandoned the place.
As in other places the locals have their own autonomous military self-defense council, similar to the maybe more widely known Manbij Military Council and more.
Syrian Democratic Forces (SDF) alliance rushing in to fill the vacuum after al-Assad's army (SAA) extremely irresponsibly just left Deir ez-Zor in what can only be assumed to be some kind of wish that the ISIL/Daesh sleeper-cells almost certainly still in the area would take the opportunity to do a major resurgence and grab it.
