An American woman who had been kidnapped was also liberated by the commandos, but is already on her way back to the United States.
Lassimouillas also expressed regret over the death of the Beninese park guide, who was killed when the French two tourists were snatched while on safari in northern Benin before being bundled across the border into Burkina Faso.
