The IS militant group has released a propaganda video which it claims shows a young boy executing two men who have "confessed to being Russian spies".
The video, released through Isis's official propaganda outlet al-Hayet Media, shows two men who it claims are "agents recruited by Russian intelligence" apparently being shot in the desert by a child who is thought to be around 10 years old.
It comes just a day after another video showed a child aged around 14 apparently carrying out a suicide bombing in the Iraqi province of Salahuddin.
A previous video showed a young boy who IS claimed took part in a suicide bombing. And while the apparent execution could not be independently verified, experts suggested that the increased use of children in the atrocities it films represented "a departure from past norms", even by IS standards.
Including captions in Arabic and English, the video claims the two men are "FSB agents", offered money to "gather information about fighters and send the information to Russia".
After they are shown "confessing" to the camera, a separate part of the video shows the two men on their knees in the desert before a militant and a boy who can be no more than 10 years old.
The militant says the men are now "in the custody of the lion cubs of the caliphate", before the child steps forward and appears to shoot the men.
