Mali's army and its Russian allies suffered a major setback and significant losses on Saturday while fighting separatists in the country's north, a spokesman for the rebels told AFP.
The West African nation's military leaders, who took power in a 2020 coup, have made it a priority to retake all of the country from separatist and jihadi forces, particularly in Kidal, a pro-independence northern bastion.
"Azawad fighters are in control in Tinzaouaten and further south in the Kidal region," said Mohamed Elmaouloud Ramadane, a spokesman for an alliance of predominantly Tuareg separatist armed groups called CSP-DPA.
"Russian mercenaries and Malian armed forces have fled," he added. "Others have surrendered."
He also shared videos of numerous corpses of soldiers and their allies.
"The Malian army has retreated," a local politician told AFP, citing at least 17 dead in a provisional toll.
"The CSP people are still in Tinzaouaten. The army and Wagner are no longer there," he said, referring to the Russian mercenary group.
Fighting also took place further south toward Abeibara, the politician said.
A former United Nations mission worker in Kidal said: "At least 15 Wagner fighters were killed and arrested after three days of fighting" adding that "the CSP rebels have taken the lead in what happened in Tinzaouaten."
Mossa Ag Inzoma, a member of the separatist movement, claimed that "dozens and dozens" of Wagner fighters and soldiers had been killed and taken prisoner.
Fighting on a scale not seen in months broke out Thursday between the army and separatists in the town of Tinzaouaten, near the border with Algeria, after the army announced it had taken control of In-Afarak, a commercial crossroads in Kidal.
Mali has been unsettled by violence by jihadi and criminal groups since 2012.
A junta led by Colonel Assimi Goita took power in 2022 and broke the country's traditional alliance with France, in favor of Russia.
