Morocco’s diplomatic and security efforts have once again emerged as a decisive factor in resolving a major crisis in the Sahel. As previously reported, Rabat used its diplomatic reach and intelligence capabilities to secure the release of Yann Vézilier, an officer with France’s General Directorate for External Security (DGSE). The agent received a presidential pardon from Mali’s transitional leader, General Assimi Goïta.
New revelations reported by French intelligence-focused media outlet Intelligence Online shed further light on the circumstances surrounding the release and confirm Morocco’s role.
The case dates back to the summer of 2025, when the French agent, operating under the official cover of second secretary at the French Embassy in Bamako, was arrested by Malian authorities over his alleged involvement in an attempted coup. The diplomat was subsequently sentenced on June 5 to 20 years in prison for undermining state security.
Faced with a deadlock that was causing serious concern within France’s security establishment, the DGSE leadership initially considered military options.
“The DGSE headquarters had tasked its Action Service (SA), which had carefully studied intervention plans,” Intelligence Online reported.
That was before French authorities found that direct efforts in several countries across the region were having no effect.
Aware of the limitations of traditional diplomacy, the French command then turned to Morocco’s expertise. The strategic decision was notably backed by the DGSE’s second-in-command, Vice Admiral Nicolas Caillez.
“Having spent most of his career in the service — apart from a stint as deputy director of operations at the Directorate of Military Intelligence (DRM) — he is highly familiar with Rabat’s intelligence services,” the French outlet said.

French intelligence services therefore opted for Moroccan mediation, reviving an approach that had already proved successful during similar crises in the region.
It was Morocco’s General Directorate for Studies and Documentation (DGED), led by Yassine Mansouri, that ultimately made the difference. By mobilizing its networks and influence with Malian authorities, the Kingdom’s intelligence service “demonstrated the effectiveness of its diplomatic reach” and succeeded in negotiating a favorable outcome.
Moroccan efforts secured the presidential pardon, clearing the way for the French agent to leave Mali permanently and reinforcing Morocco’s central role as an actor for stability and an essential mediator in the Sahel.
The success follows Morocco’s diplomatic efforts in Burkina Faso. In December 2023, four French officials from the General Directorate for External Security (DGSE), who held diplomatic visas, were arrested in Ouagadougou on espionage allegations.
After a year of diplomatic deadlock, facilitation by Morocco helped secure their release in late December 2024.
French President Emmanuel Macron then called King Mohammed VI to express France’s gratitude, as the Élysée Palace confirmed to Agence France-Presse.
“In Bamako as in the Burkina Faso case, senior French intelligence officials relied on successful mediation by Moroccan intelligence services,” Intelligence Online concluded.
