NSO website received information saying a shipment of anti-aircraft missiles known as MANPADS was delivered to “People’s Protection Units YPG” in Efrin canton in Aleppo northern countryside last week.

Information received from several sources said USA agreed in secret to send MANPADS to YPG as an independent secret deal between USA and YPG outside the support of US-led anti-ISIS coalition that supports YPG-dominated “Syrian Democratic Forces SDF”.

The source told NSO that US representatives told YPG commanders who received the shipment to not use it unless Efrin city and Kurdish-majority areas were threatened, and assured them that Turkey could launch a military operation to take Tal Rifa’at and dozens of villages around it which doesn’t belong to Efrin canton and in this case the missiles shouldn’t be used.

The shipment which supposed to be followed by others reached Syria from Kurdistan Iraq through Assad regime-held area in Aleppo eastern and western countryside to YPG-held Efrin canton but local sources confirmed that Russian or Assad regime didn't protest against these missiles.

This shipment comes after the escalation of Turkish threats to PYD militias in Manbij and Efrin, Turkish President Erdogan said in a speech at the Parliament on Tuesday that Turkish army will continue “Euphrates Shield” operation which started in August 2016 in Jarablus and al-Bab in Aleppo eastern countryside, Erdogan also threatened to destroy PYD militias bases in Efrin if they didn’t surrender during a speech in AKP meeting in Elazig city.

Turkey considers “Democratic Union Party PYD” and its armed militias as terrorist groups and the Syrian wing of “Kurdistan Workers Party PKK” while PYD and its military wing YPG considered powerful ally for USA in its fight against ISIS in Syria.

For many years of fighting in Syria USA refused to send MANPADS to vetted FSA group to use it against Assad warplanes and expressed many times it won’t allow this in fear of these weapons will reach extremist groups, however, several cases of using this kind of missiles against Assad warplanes have been seen without specific information of its origin.
