The Turkish military fired "warning shots" early Friday against a convoy of 30-40 vehicles carrying People's Protection Units (YPG) terrorists and weaponry into northern Syria's Afrin.

Military sources said an unmanned aerial vehicle detected the convoy attempting to enter Afrin from Jazirah district.

On Wednesday, Turkey carried out warning strikes near Afrin after pro-Syrian government forces tried to enter the region to support YPG forces. The convoy of 40-50 vehicles retreated after the artillery fire.
