Surrounded by the Syrian opposition since January 2013 opposition fighters in the area have claimed the FN-6 MANPADS are part of a no-fly zone they've imposed around the air base.

Another opposition figure involved in supplying the rebels said there had been a noticeable relaxation in recent days of the strict restrictions the US and Turkey had put on arms flows over the Turkish border. He claimed a Syrian army helicopter and a Mig warplane had been shot down in the past two days, for the first time by imported missiles.

Several rebel commanders and fighters told Reuters that a shipment which reached Syria via Turkey last month comprised shoulder-held and other mobile equipment including anti-aircraft and armor-piercing weapons, mortars and rocket launchers.
