On Sunday, Russian officials confirmed that Yevgeny Prighozin was among those killed in a plane crash last week. Prighozin was chief of the Wagner mercenary group, which has carried out operations in a number of African countries. Over the last year, many countries in the Sahel region have moved away from their former security partners in the west. And Mali, which is struggling to contain secessionists and Islamist militants, has turned to Wagner to bolster their security. So, what might Prighozin’s death mean for those countries that are relying on Wagner?
