One of his posts shows the gravestone of a man who Stimson said was from Northern Ireland and had Russian roots.
According to Stimson, the man previously served in the British Army but turned to Russia after being traumatised by his service in Iraq.
Stimson says he was killed in the opening weeks of the Russian invasion of Ukraine. His gravestone is inscribed with his likeliness alongside the word “Irlandetz”, which means “Irishman” in Russian.
Another image shows Stimson posing with men in Russian army uniforms who, he says, are from Morocco.
“Good luck to my Moroccan brothers Saeed and Mahmood,” the caption states. “God/Allah be with you guys,” it adds.
Stimson could not be contacted for comment.
