Patrick Cockburn reporting from Damascus:

It is one of the most horrifying videos of the war in Syria. It shows two men being beheaded by Syrian rebels, one of them by a child. He hacks with a machete at the neck of a middle-aged man who has been forced to lie in the street with his head on a concrete block. At the end of the film, a soldier, apparently from the Free Syrian Army, holds up the severed heads by their hair in triumph.

The film is being widely watched on YouTube by Syrians, reinforcing their fears that Syria is imitating Iraq’s descent into murderous warfare in the years after the US invasion in 2003. It fosters a belief among Syria’s non-Sunni Muslim minorities, and Sunnis associated with the government as soldiers or civil servants, that there will be no safe future for them in Syria if the rebels win. In one version of the video, several of which are circulating, the men who are beheaded are identified as officers belonging to the 2.5 million-strong Alawite community. This is the Shia sect to which President Bashar al-Assad and core members of his regime belong. The beheadings, so proudly filmed by the perpetrators, may well convince them that they have no alternative but to fight to the end.

The video underlines a startling contradiction in the policy of the US and its allies. In the past week, 130 countries have recognised the National Coalition of Syrian Revolutionary and Opposition Forces as the legitimate representatives of the Syrian people. But, at the same time, the US has denounced the al-Nusra Front, the most effective fighting force of the rebels, as being terrorists and an al-Qa’ida affiliate. Paradoxically, the US makes almost exactly same allegations of terrorism against al-Nusra as does the Syrian government. Even more bizarrely, though so many states now recognise the National Coalition as the legitimate representative of the Syrian people, it is unclear if the rebels inside Syria do so. Angry crowds in rebel-held areas of northern Syria on Friday chanted “we are all al-Nusra” as they demonstrated against the US decision.

More on that video:

I have not met a Syrian in Damascus who has not seen it. It is having great influence on how Syrians judge their future, but the mainstream media outside Syria has scarcely mentioned it. Some may be repulsed by its casual savagery, but more probably it is not shown because it contradicts so much of what foreign leaders and reporters claim is happening here.
