We are now seeing a very complex, yet important situation take place between the Syrian towns of Afrin and Azaz. U.S. backed SDF (Syrian Democratic Forces) made up of Kurds, Arabs, Assyrians, and Armenians, have started fighting Turkish/Gulf backed Islamist rebels. The situation on the ground is still murky, yet videos of the two groups fighting each other have emerged, along with heavy rhetoric from each side. Interestingly enough, there are FSA (Free Syrian Army) groups on both sides. As well, two of the groups fighting against the U.S. backed SDF are in the CIA TOW missile program.
Part of the reason we are seeing these clashes now is because of renewed talk of a long-awaited "Safe Zone" promised by Turkey for months, yet has gotten added urgency now following the shooting down of a Russian Su-24 jet. As well, the SDF have been accused of using Russian air-strikes as cover to move against the Islamist groups around Azaz.
If there is one area where the already complex Syria conflict is at its most complex, this is it.
