The boy is first seen in the back of a truck with an IV in his arm. It is unlikely Zenki would have taken the time to do this if they were simply going to execute him. This suggests he may have been kidnapped.
The Zenki rebels taunt him, calling him a "dog of Bashar." It is here that they state are going to kill him.
One fighter then lays the boy out in the back of the pickup truck.
The boy is then beheaded to joyous calls of "Allahu Akbar."
After footage of this brutal incident was posted online, pro-opposition analysts/propagandists went into a panic trying to whitewash the crime, or to claim that this doesn't represent the Zenki group as a whole.
Some tried to portray collateral airstrike casualties as being on the same level as the beheading of a child.
The Ex US ambassador to Syria is speaking as if Zenki could still be a viable group for US support, even after beheading a child.
The pro-opposition analysts/propagandists were quick to defend Zenki because the group had been labeled moderate by the US Government. Zenki is part of the "Fatah Halab" coalition alongside many Free Syrian Army groups. Weapons had been supplied to them by the CIA "Train and Equip" program. TOW anti-tank guided missiles were first delivered to Zenki in 2014. They can be seen using US supplied TOWs below.
Zenki had last used TOW missiles as late as June 2016.
Harakat Nour al-Din al-Zenki is not a moderate rebel group, that has been made clear by this execution. In addition to this, Zenki has been a close ally of Jabhat al-Nusra (al-Qaeda's Syrian branch) for some time. Recently, both Zenki and JaN fought alongside each other at Mallah farms, Aleppo.
Zenki filmed a BMP-1 belonging to Jabhat al-Nusra, both groups are going into battle together.
Jabhat al-Nusra even admitted that they worked together with Zenki at Mallah Farms in a press release.
Zenki's leader has also been seen with Jabhat al-Nusra's Abdallah Muhaysini.
