The military regime in the West African state had turned to the notorious Wagner group in 2021, seeking support in fighting jihadist and separatist forces.

On Monday the Russian outfit - which has now morphed into a group named Africa Corps - said it had joined Mali’s military in “fierce battles” against separatist rebels and jihadist militants last week.

However, the separatists launched a major attack, killing an estimated 20 to 50 mercenaries, sources close to Africa Corps told the BBC.
