Snipers of the Russian National Guard killed four prisoners today who took prison guards hostage and declared allegiance to the Islamic State, Russian media reports.
The National Guard said the rebel prisoners had been "neutralized" and that all the hostages had been freed, although the number of hostages was not immediately specified.
In the prison in the city of Surovikin in the Volgograd Region, some of the prisoners attacked the prison guards and the prison administration and took hostages.
Prisoners attacked prison employees with knives during the session of the disciplinary commission, and took them hostage.
Before the prisoners were killed, state news agency TASS said four victims were taken to a local hospital and two were in serious condition.
Unconfirmed reports on Telegram say one or two people have died.
Court records show that the hijackers were from former Soviet countries in Central Asia, and all suspects in the attack on the concert hall are from Tajikistan.
The video, whose authenticity has not been officially confirmed and was published by several Russian media outlets, shows a blood-soaked room with four men on the floor covered in blood, some appearing dead, and two more men standing, filmed by a third person speaking in Arabic. That person then declares his affiliation with the Islamic State group in Russian.
In the 46-second video, one of the men holds a knife in one hand and holds the neck of what is believed to be one of the prison guards with the other.
In mid-June, several members of the Islamist organization Islamic State were killed when they took prison officers hostage in a prison in southwestern Russia, in the Rostov region adjacent to Volgograd.
Russia has repeatedly been the target of attacks for which this Islamic organization took responsibility, although the influence of the Islamic State in Russia is small.
