This video was recorded by a former member of the Islamic State of Iraq and the Levant (ISIL) in late January, 2014.
It shows ISIL members executing three men in view of a crowd in a public square in Raqqa, northern Syria.
Before the executions one of the ISIL members shouts that the men are accused of betraying Islam and spying for the (Assad) regime.
"In order to follow the Shari'a, we have to execute these men because they are betrayers of Islam. They are spies of the regime and they have betrayed us. Our brothers in ISIL were able catch these men who we will execute in the name of God."
After the killings the bodies of the three men are thrown into a canyon in an area known as Houtat Suluk, northeast of Raqqa.
Local residents allege that more than 400 bodies have been dumped in this same location since ISIL took control of areas of northeastern Syria in mid January. This claim is unconfirmed.
