At the same time, the Kremlin denies any official links with the group.

The SBU Security Service of Ukraine has earlier revealed evidence of Wagner troops' involvement in war crimes in the territory of Ukraine.

"In the course of the Debaltseve assault by the regular Russian units and terrorists on February 21, 2015, officers of the Ukrainian special service taped telephone conversations of the Russian special services' unit representatives named Private Military Company (PMC) Wagner. The received information is another evidence of Russia military aggression and testifies to severe losses of Russian servicemen in the course of 'hybrid warfare' against Ukraine," the SBU said on its website.
