ISIS beheads Russian, tells nation ‘we will kill your children’

The ISIS media group in Raqqa, Syria released another execution video. This time, the victim is Khasiev Magomid, an alleged member of the Russian Federal Security Service, or FSB – successor to the Soviet-era KGB.

Magomid admitted he entered ISIS territory to gather names, photos, and information about Daesh fighters.

The video, titled "You Shall be Disappointed and Humiliated O Russians," shows the standard Daesh execution video, with Magomid on his knees. His captor, standing above him, claims he's a Russian national from Chechnya before cutting the victim's throat.

The video also criticized Russian President Vladimir Putin and threatens all of Russia's citizens.

"Listen, Putin the dog, the [Assad] regime bombed us before you came and then America and its coward allies bombed us. Oh Russian infidels, we've been waiting for you…You have been taken to a new defeat. You will find no security in your homes and we will kill your children for every child you killed here."

Putin vowed retaliation against ISIS for the bombing of a Russian commercial jet over the Sinai Peninsula in October 2015. There has not yet been any official reaction from the Russian security forces or foreign ministry over the murder of Magomid.

In January 2015, Chechen leadership told the Interfax News Agency, Russia did have an intelligence network inside ISIS.

"This allows us to track the movement of those who are of interest to us," said Ramzan Kadyrov, former Chechen rebel and now head of the Chechen Republic. "Moreover, it allows us to send those who, even as a joke, direct the barrel towards Russian on an eternal trip with a one-way ticket."

Kadyrov confirmed the Russian in the video was indeed a Chechen citizen and expressed his desire to join the anti-terror operation in Syria with Chechen special operations units. He promised to avenge Magomid's death.

"Chechens remember, know and will not leave this unanswered," he said.  "Those who slaughtered our citizen will not live long."
