The footage, which has not been verified, shows members of the Free Syrian Army gathering around a camera. The eight men are seen sitting in front of a rebel flag as they sing into a microphone, with two rifles propped up in front of them.
The 30-second clip shows one of the men picking up a phone and holding it up to take a picture of him and the other rebels. A clicking noise can be heard moments before a sudden blast rocks the room, with flames and smoke obscuring the camera's view.
When the dust clears, the camera has been blown backwards onto the floor and is pointing towards a ceiling fan.
The rebels can be heard shouting 'Allahu Akbar' - meaning 'God is great' - as they jump over the camera to help their comrades.
The fact that the camera was not destroyed and that the other men in the room appear uninjured suggest the bomb may have been smaller than others seen used by rebels and ISIS in Syria.
It is not known if anyone was injured or killed in the blast.
