Again Winston, you are ignoring decades of the Kurds and Turkey going at it. As many have said, there is very little way to determine who is SDF or PKK. "During the 1980s Turkey began a program of forced assimilation of its Kurdish population. This culminated in 1984 when the PKK began a rebellion against Turkish rule attacking Turkish military and civilian targets. Since the PKK's militant operations began in 1984, 37,000 people have been killed. The PKK has been continuing its guerrilla warfare in the mountains. However, since 1995, and especially since the AK Party came to power there have been numerous reforms and the situation has greatly improved. As a result, the fighting is limited to approximately 3000 fighters."
