Isis has released a new video on Tuesday which shows how a child executioner shoots two Russian spies.
However, the latest recording appears to be the first showing a child executioner. The same boy was earlier featured in another Isis propaganda video showing jihadi recruits from Kazakhstan.
The age of the boy who carried out the killing is said to between 10 years or less, speaking of his ambitions to grow up is to "kill infidels" and identifying himself as "Abdullah" from Kazakhstan.
The two Russians claims they infiltrated Isis to gather information for Russian intelligence agency FSB (Federal Security Service). One says he was tasked with killing a leading Islamist figure.
