A shocking video has emerged from a Syrian rebel group who was vetted by the US government.
In the video, fighters from a US-backed Syrian militant group have been filmed brutally beheading a Palestinian child, reported to be as young as 10 years old.
The video captures Nour al-Din al-Zenki fighters in the back of a truck with a child they claim is an al-Quds soldier supporting Assad's Syrian forces.
One of the fighters shouts 'Allahu Akbar' meaning 'God is great' after taking a small knife to the boy's throat and cutting off his head in the Palesinian refugee Handarat Camp in Northern Aleppo.
Syrian rebel groups as well as ISIS have enjoyed funding, training and weapons from the US government in an attempt to overthrow the Assad regime. The question that needs to be asked is at what point did the US government become aware of the extremist nature of these groups and why did they continue to fund them.
