MOSCOW, Dec. 3 (UPI) -- The Islamic State is claiming to have beheaded an alleged Russian spy in an execution video released Wednesday.
In the unverified video filmed in Syria -- titled You Shall be Disappointed and humiliated O Russians -- a man wearing an orange jumpsuit is seen kneeling in front of another man who is standing above him clutching a knife.
The man kneeling, the alleged spy who identified himself as Magomed Khasiyev, said he is a Russian national from the Chechen Republic.
The unmasked captor spoke in Russian before executing the prisoner by cutting his throat. The Islamic State has repeatedly threatened Russia after Moscow began airstrikes in Syria in late September.
Russian bombardments have targeted opponents of Syrian President Bashar al-Assad's regime, which include the Islamic State and several Syrian rebel groups -- some who are considered moderate allies by Western powers.
The in the video said Russia's bombardments "have done nothing but kill peaceful Muslims."
"You will not find peace in your homes," the executioner said in the video, threatening Russia. "We will kill your sons... for each son you killed here. And we will destroy your homes for each home you destroyed here."
The executioner also makes a direct threat to Russian President Vladimir Putin.
"Putin, you dog, we attacked Assad prior to your arrival as well as the Americans and their allies. We will also attack you," the apparent Islamic State militant says.
