US-ARMED terrorist leaders in Syria tried to distance themselves yesterday from their foot soldiers’ brutal beheading of a Palestinian refugee child.

Their denials came as the US State Department hinted that it might halt arms shipments to its head-chopping proxy forces.

Video emerged on Tuesday of members of Harakat Nour al-Din al-Zinki taunting the boy before severing his head with a knife in the back of their pick-up truck.
