Islamic State (ISIS) released a new scare video Wednesday, this time targeting the Russians. 

The video, entitled “You Shall be Disappointed and Humiliated O Russians,” shows the beheading of an alleged Chechen spy – a 23 year-old who admits on camera to passing along information to Moscow from Syria and Iraq about the 605 Russian citizens who left to join the jihadists. 

The “spy” added that the Russians are having difficulty keeping track of the foreign nationals, due to the common practice of changing names upon joining the organization. 

The captor speaks in Russian before decapitating his victim, stating, “[Russian President Vladimir] Putin, you dog, we attacked [Syrian President Bashar] Assad prior to your arrival as well as the Americans and their allies – we will also attack you.”

Russia began airstrikes on ISIS in Syria in late September. 

The film was shot in the ISIS “capital” of Raqqah, Syria.
