We review key developments in Syria, including the Syrian Democratic Forces advancing against ISIS north of Raqqa, the USA arming Kurdish forces fighting in Raqqa and claims Washington is also aiding Syrian rebel groups operating in the south of the country.
However, the US recognizes the separate People's Protection Units of the Y.P.G.as an ally with the most experienced fighters.
Turkey began building the wall in 2014 to boost its security by preventing infiltrations of Kurdish militants and Islamic State group fighters as well as refugees from Syria.
So far, it remained unknown what the Pentagon was sending to the Kurdish elements of the Syrian Democratic Forces (SDF).
Silo's warning contrasts starkly with earlier comments made by the PYD representative in Iraqi Kurdistan, Gharib Hesso, who indicated that the PYD would be interested in allying with the PMUs in order to build a new "corridor" in Iraq to Baghdad in order to circumvent an embargo placed on YPG-controlled territory in northern Syria. "But if the road is closed, we will resist", he said, as reported by Middle East Eye. It is also anxious that the weapons will end up in the hands of the Kurdistan Workers Party (PKK), a group it has been fighting for decades.
However, the USA believes the Kurdish elements of the Syrian Democratic Forces (SDF) will be essential to Raqqa's downfall.
Washington believes that YPG fighters are the only force now qualified to recapture Raqqa from ISIS.
During his visit to Washington in May, President Recep Tayyip Erdogan also attempted to convince President Trump to rescind his support for the YPG but appears to have failed.
"These weapons could be used against all humanity, not just Turkey".
Many players in Syria's complex and multi-sided civil war are anxious that the new influx of weaponry could further destablise the country if weapons are leaked or diverted to other groups once Isis militants are defeated.
Turkey considers the Kurdish forces to be "terrorists" and fears any weapons sent to the YPG could end up in the hands of the PKK.
