Commenting on the recent revelation by an al-Nusra commander that the US is supplying the extremist groups with its weapons through third countries, Gordon Duff, Senior Editor of Veterans Today website says the aim of the "no-fly" zone pushed by Washington has only one purpose – to provide air cover to the terrorists.

"All the ideas of the ceasefire were predicated on the idea of disengagement. Disengagement implies that the forces of the US-backed Free Syrian Army (FSA) and others, like al-Nusra Front, or Jabhat Fatah al-Sham that it now calls itself, and of course al-Qaeda and Daesh (ISIL/ISIS) are mingling together. But the US policy had been only to arm the FSA because they were supposedly fighting ISIS and al-Nusra," Gordon Duff said in an interview with Iranian English language news network Press TV.

Now, the expert says, it is openly admitted that all the above groups are "totally intermingled."

The remark comes in the follow up to the recent article in the German Kolner Stadt-Anzeiger newspaper. On Monday, it published an interview with Jabhat al-Nusra unit commander Abu Al Ezz, who revealed that Washington is delivering US weapons to the group, including TOW missiles through the third countries.

The militant added that American instructors were in Syria to teach them how to use the new equipment.

"The American allies are not only supplying weapons, they are supplying tanks and trucks directly to al-Nusra units," the Veterans Today Senior Editor told Press TV.

"The difficulty is: how there can be any negotiation, how ther can be an idea of a "no-fly" zone while these forces are totally integrated. While the American-backed forces are totally integrated with the terrorist organizations fighting against the Damascus government?" he questioned.

"There is no way for a no-fly zone to be anything other than a varied air cover, in fact, a legal air cover for the terrorist operations against the Syrian people," he then said.

"Calling it anything else and calling all what America had said all along is double-speak, and it is the only way this can be seen," he finally stated.
