Mali’s judicial system has handed down a 20-year prison sentence to a French national with diplomatic status, found guilty of state security offences. The man, identified as Yann V., has been held in Bamako since his arrest in August 2025.

The verdict was delivered on Thursday by the criminal chamber of the specialised counterterrorism unit. In addition to the prison term, Yann V. was banned from entering Mali for 20 years and ordered to pay a fine of 5,400 euros.

According to Malian authorities, the suspect was arrested on August 13, 2025, during an operation by the State Security service, the country’s intelligence agency. He was officially assigned to the French embassy in Bamako at the time and was apprehended alongside several officers of the Malian Armed Forces (FAMa).

Those military personnel have since been dismissed from the army. They are accused of participating in an espionage network and conspiring to destabilise Mali’s transitional institutions and prepare a coup. Their trial has not yet taken place.

France has categorically rejected the accusations. Responding to the verdict, the French foreign ministry denounced the charges as baseless, insisting that the agent was carrying out a security cooperation mission. Paris maintains it has never been involved, directly or indirectly, in any effort to destabilise Mali.

The case had already sparked serious diplomatic tensions between the two countries. Following the arrest, France suspended its counterterrorism cooperation with Mali and ordered two Malian diplomats to leave its territory.

Since the military came to power after the coups of 2020 and 2021, relations between Bamako and Paris have deteriorated sharply. Malian authorities have progressively scaled back cooperation with Western partners, especially France, while strengthening political and security ties with Russia. The sentencing marks a key moment in African current affairs, reflecting the broader challenges of governance in the Sahel region.
