Supporters and soldiers lay flowers at a new statue of Yevgeny Prigozhin in bronze at his grave in St. Petersburg.
Prigozhin was the leader of the notorious Wagner paramilitary group, which fought alongside Russian forces in Ukraine, but last summer he rebelled against the power in Russia.
Two months later, Prigozhin died in a plane crash. Intelligence reports in the West claim that Vladimir Putin made the decision to have Prigozhin killed – which the Kremlin has denied.
Prigozhin would have turned 63 on Saturday.
