IS video purports to show boy executing 'Russian spies'

The Islamic State jihadist group released a video today purporting to show a young boy executing two men accused of working for Russian intelligence services.
The video shows the two men apparently being shot dead by the child after being interrogated on camera about their alleged attempts to infiltrate IS in Syria.
Entitled "Uncovering an Enemy Within" in English, the video is narrated in Russian and opens with the interrogation of one of the men, who says he is a Kazakh citizen.
He says he was recruited by Russia's Federal Security Service (FSB) to get close to an unnamed IS fighter.

The second man, who does not give his nationality but says he worked for the FSB in Russia previously, says he was tasked with killing an unnamed IS fighter.
Both men say they were told to collect and transmit information about IS fighters in Syria.
After the interrogations, the video cuts to an outdoors scene, where a bearded adult IS fighter in military-style clothes is standing next to a young boy armed with a pistol.
