DAKAR, Senegal (AP) — The Russia-backed Wagner Group said Friday it is leaving Mali after more than three and a half years of fighting Islamic extremists and insurgents in the country. Despite Wagner’s announcement, Russia will continue to have a mercenary presence in the West African country. The Africa Corps, Russia’s state-controlled paramilitary force, said on its Telegram channel Friday that Wagner’s departure would not introduce any changes and the Russian contingent will remain in Mali.
