Ukraine has criticised Mali's decision to sever diplomatic ties, calling it short-sighted and hasty. This decision followed comments from Ukraine's military spy agency about the recent clashes in northern Mali, where Tuareg rebels claimed responsibility for killing 84 Russian Wagner mercenaries and 47 Malian soldiers. This was Wagner's most significant defeat since assisting Mali's military against insurgent groups two years ago. Ukraine denied involvement, stating no evidence was provided. After the spy agency mentioned that rebels had received ‘necessary’ information for the attack, Mali interpreted this as an admission of Ukraine's involvement, condemning it as a violation of sovereignty and support for terrorism. Senegal summoned Ukraine’s ambassador over related accusations. These events occur amid deteriorating relations between the West and Sahel nations, which have expelled French and US forces and turned to Russian mercenaries for security following recent military coups in Mali, Burkina Faso, and Niger.
