The Wagner Group is linked to a massacre of 500 people in a village in Mali, a UN report found.
Outside the war in Ukraine, the event is the worst atrocity associated with the Wagner Group, The Guardian reported.
But the military group also has various ties to African countries, according to the Associated Press, and has been accused of supporting other violent military operations in the region, per The Guardian.
In the past few years, Russia has had a commanding presence in multiple African countries, with the assistance of the Wagner Group, to advance its global power.
More than a year ago, the Kremlin-linked military contractor group began working with Malian armed forces to quell Islamic extremism in the country, per the AP.
