(AFP) - Around 170 people were "executed" in attacks on three villages in northern Burkina Faso a week ago, a regional public prosecutor said Sunday.
Aly Benjamin Coulibaly said he received reports of the attacks on the villages of Komsilga, Nodin and Soroe in Yatenga province on February 25, with a provisional toll of "around 170 people executed".
The attacks left others wounded and caused material damage, the prosecutor for the northern town of Ouahigouya added in a statement.
He said his office ordered an investigation and appealed to the public for information.
Survivors of the attacks told AFP that dozens of women and young children were among the victims.
Local security sources said the attacks were separate from deadly incidents at a mosque and a church in northern Burkina Faso that also happened a week ago.
Authorities have yet to release an official death toll for those attacks.
Burkina Faso has been grappling with a jihadist insurgency waged by rebels affiliated with al Qaeda and the Islamic State (IS) group that spilled over from neighbouring Mali in 2015.
The violence has killed almost 20,000 people and displaced more than two million in Burkina Faso, one of the world's poorest countries situated in the Sahel, a region wracked by instability.
Anger at the state's inability to end the insecurity played a major role in two military coups in 2022. Current strongman Ibrahim Traore has made the fight against rebel groups a priority.
