The Wagner Group’s presence extends from Syria to Africa, projecting the Kremlin’s global influence with mercenaries accused of using brutal force and profiting on mineral wealth. But that was under Yevgeny Prigozhin. In what could have been his final video released this week, he boasted that Wagner is “making Russia even greater on all continents and Africa even more free.” On Wednesday, a private jet carrying Prigozhin and his top lieutenants of the mercenary group crashed northwest of Moscow, two months after he led an armed rebellion that weakened the authority of President Vladimir Putin. That crash has raised questions about the future of the Wagner Group without Prigozhin.
