French special forces carried out the raid under cover of dark over the night of Thursday-Friday, supported by U.S. intelligence and troops from France’s Barkhane operation deployed in the Sahel region to counter militants.
All four hostages were safe, President’s office said, adding that a U.S. woman and a South Korean woman were also freed in the covert operation.
“The precise and determined actions of French soldiers allowed us to take out the kidnappers while protecting the lives of the hostages,” France’s army chief said in a separate statement, describing the militant group as “terrorists”.
France, the former colonial power in the region, intervened in Mali in 2013 to drive out militants, who had occupied the north of the country and has since kept about 4,500 troops in the Sahel.
The region, a vast, sparsely-populated desert area, has seen a spike in violence by militant groups linked to al Qaeda and Islamic State in past years, highlighting the difficulty international partner’s face in restoring stability.
France’s defence ministry identified the fallen soldiers as two elite naval commandos.
Burkina Faso’s President Roch Kabore hailed the hostages’ release and offered condolences to the soldiers’ families.
“The joint military intervention that allowed us to achieve these results shows our common engagement in fighting against the forces of evil,” said Kabore in a Facebook post.
The two French tourists were kidnapped on May 1 in Benin’s Pendjari National Park, home to some of the region’s last big populations of African bush elephant, West African lions, hippo and buffalo.
The park lies on Benin’s northern frontier with Burkina Faso. Their safari guide was found dead, his body riddled with bullets, and their vehicle burned.
