TO GO WITH AFP STORY BY W.G. Dunlop - An image grab taken from a video released by Al-Hayat Media Centre on January 13, 2015 and reportedly taken on November 24, 2014 allegedly shows an Islamic State (IS) group fighter speaking to the camera next to a child (L), who is identified in an earlier propaganda video as Abdullah from Kazakhstan, before the child executes two men (front) accused of working for Russian intelligence services at an unknown location. The video shows the two men apparently being shot dead by the child after being interrogated on camera about their alleged attempts to infiltrate the Islamic State (IS) group in Syria. The video is one of many examples of IS propaganda aimed at spreading its beliefs to a younger generation to aid in recruiting and perpetuate the "caliphate" the group declared in areas it holds in Iraq and Syria.
