At around 3pm, a convoy escorting Burkinabe soldiers and troops from the elite Rapid Action Group for Surveillance and Intervention (GARSI) were ambushed by JNIM fighters near the village of Dounkoun. Several vehicles were destroyed and others were captured by JNIM.[3] The ambush was in retaliation for the killing of JNIM commander Sidibe Ousmane and religious trainer Bande Amadou. Ousmane and Amadou had been killed the day prior by Burkinabe forces between Diamasso and Bouni in Kossi Province.[2]
Twelve Burkinabe soldiers were killed in the ambush at Dounkoun and eight others were injured. Some soldiers were reported missing initially by the Burkinabe government, but they were found the next morning.[3]
