Two US-backed groups clash in northern Syria
Jaysh al Tahrir, a group that has received several US TOW anti-tank missiles in the past, fought with the Kurdish-led Syrian Democratic Forces (SDF) in northern Aleppo. The SDF is the main anti-Islamic State fighting force for the United States and has received considerable support from the West.
