Wearing a black Isil headband and military-style fatigues, the boy announced to the camera beforehand that “we are going to kill the kuffars (non-believers) over there”. He is then seen standing beside the car’s burnt-out remains, triumphantly punching the air and shouting: "Allahu akbar"
In the latest video, believed to have been shot in Raqqa, Syria, he is accompanied by a masked man who issues a threat to David Cameron for arming groups in Syria who are fighting the jihadists.
"You will never fight us except behind fortified fortresses or behind walls,” says the man, speaking in an English accent.
"So no David Cameron….you’ve only done two things. Firstly, when you sent your spies to Syria and when you authorised for your men, thousands of miles away, to push a button to kill our brothers who lived in the West.
"So today, we’re going to kill your spies the same way they helped you kill our brothers.
"So prepare your army and gather your nations as we too are preparing our army"
