Algeria’s president, Abdelmadjid Tebboune, has offered to mediate between Mali’s military-led government and northern rebel groups, including Tuareg and Arab nationalists, amid escalating regional tensions. However, he clarified that he would only step in if formally invited by Mali. His statement comes after Mali's junta withdrew from a previous Algeria-brokered peace deal and replaced UN peacekeepers with Russian Africa Corps mercenaries, formerly Wagner. Algeria has refused to tolerate mercenary forces on its 1,400 km shared border, despite its own longstanding ties with Russia. Mutual accusations have intensified, with both countries alleging drone strikes and cross-border incursions. Mali has accused Algeria of harbouring militants who conduct attacks from Algerian soil, a claim Algiers denies. The withdrawal of the UN’s MINUSMA peacekeeping force in 2023 has left a security vacuum in northern Mali, now filled by armed factions and foreign operatives. Tebboune’s call for diplomacy reflects Algeria’s concern over instability and the threat of wider conflict spreading across the Sahel region.
