The Russian National Guard said its snipers killed four hostage-takers when security forces stormed a prison in the southwestern region of Volgograd after knife-wielding prisoners reportedly launched a deadly attack on guards and held some staff hostage.

The Federal Penitentiary Service (FSIN) said in a statement that four prison guards died on August 23 after four inmates took eight guards and four other inmates hostage at the correctional colony No. 19 in the town of Surovikino in the Volgograd region.

"The perpetrators inflicted stabbing wounds of various types on four prison employees, three of whom died. The other four, who resisted, were hospitalized, and one of them died in hospital," the FSIN's statement said, adding that four other inmates also were wounded in the hostage-taking crisis.

Media reports as the incident began said several people died when the hostage-taking took place while a disciplinary commission was in the penitentiary.

Telegram channels close to the penitentiary service issued a video showing four inmates who called themselves "Islamic State fighters" wielding knives and standing next to three bodies in FSIN uniforms and another uniformed person who was injured.

One Telegram channel identified the four inmates as two men from Uzbekistan and two from Tajikistan, three of whom are serving terms for illegal drugs and one for inflicting serious damage to a person’s health. That information has not been confirmed officially.
