ISIS terrorist identified as part of Turkish-backed forces ranks in Afrin

An ISIS terrorist has been visually identified among the ranks of Turkish-backed forces in the Afrin area of Aleppo Governorate. He now officially serves with the Free Syrian Army.
Sources say that there are hundreds of ISIS fighters who fled to Turkey over the years and then joined the FSA to fight against the Kurdish YPG in Afrin alongside Turkish forces.
Even without fleeing to Turkey, ISIS and FSA fighters have been known to swap ranks in the past based on convenience.
