Sixteen security forces were killed in an ambush in Burkina Faso's insurgent-hit north on Wednesday, three security sources said on Friday.
The attack took place near the village of Koumestenga in Namentenga province in the Centre-North region, one of several areas plagued with jihadist activity.
One army source and two sources in the gendarmerie who did not wish to be named confirmed the attack and gave the death toll on Friday. They said seven gendarmes and nine members of a volunteer self-defence force had been killed.
