 This is the World. I'm Marco Werman. You likely remember the Russian paramilitary outfit called the Wagner Group. It was in the news quite a bit up until the militia launched an uprising against the Kremlin one year ago. Wagner's top commander died in a plane crash and the group was disbanded. But the story does not just end there. Some of those militia units now serve under a new name, often in conflict zones across Africa. Allegations of atrocities by Russian mercenaries in Africa had been circulating without verification.
