UPDATE 28.12.2018: This is an old photo, which has been actively circulating online in connection with the recent developments in the area of Manbij.
A fresh photo has appeared online showing a Russian soldier with a patch of the Manbij Military Council of the Syrian Democratic Forces (SDF). The SDF is a Kurdish-dominated group which controls the area of Manbij as well as most of northeastern Syria.
On December 28, the Kurdish People’s Protection Units (YPG), which are the core of the SDF, announced that they are inviting the Syrian Army to take control of Manbij to protect it from a possible Turkish invasion.
A group of Russian and Syrian troops were already deployed in the village of Arima, west of Manbij, earlier this week.
