Testimonies from refugees in Mauritania reveal severe human rights abuses committed during counter-insurgency operations in Mali involving Russian mercenaries formerly associated with the Wagner Group. Witnesses describe arbitrary detentions, torture, and extrajudicial killings as civilians were accused of aiding jihadist insurgents. One former shopkeeper recounted being detained, threatened, and mistreated before later fleeing the country with his family. Others reported loved ones killed without explanation or being beaten while performing everyday tasks like herding livestock. Human rights monitors say these actions have spread fear and driven tens of thousands to flee across the border. Although Wagner has formally withdrawn, many of its operatives are now part of Russia’s Africa Corps, and concerns remain that abuses continue under a new name. Calls are growing for accountability and justice for victims, as communities struggle with trauma, displacement, and the loss of safety in their homeland.
