Tensions between Russia’s military and the private military contractor Wagner Group have reached a boiling point, with the group’s founder Dmitry Utkin accusing top brass of treason.

The accusations come after Ukraine reported a rift between the Russian military and Wagner Group, a private military contractor with ties to the Kremlin.

Utkin, who goes by the nom de guerre “Wagner,” accused top Russian military officials of “treason” in an interview with Al Jazeera English. He alleged that the officials had failed to adequately support Wagner Group fighters in a conflict in the Central African Republic.

Utkin’s claims have been met with pushback from the Russian government. In response to the accusations, a spokesperson for the Kremlin said that “there is no basis for such accusations.”

The Wagner Group has been accused of using pop culture to recruit new fighters, according to a report from The Wall Street Journal. The group has used music videos and social media to attract potential recruits.

The Associated Press reported that Utkin had also slammed the Russian government for its lack of support for the Wagner Group.

The rift between the Russian military and the Wagner Group has created a tense situation, with no clear resolution in sight.
