The military convoy set out with the task of supplying cities and military bases in eastern Burkina Faso besieged by jihadist groups.[4] The first group of soldiers, made up of Rapid Intervention Brigades 5 and 9 (BIR), left the city of Dori on April 27 and headed out towards Mansila.[5] Mansila had been under siege by JNIM since 2020, and had not been supplied by the government by land since December 2022.[5] On the first day of the journey, the convoy committed its first massacre after being hit by a mine. Thirty people were killed in Niagassi, including fifteen women and nine children, in response to the explosion.[4] The convoy then committed three massacres in Ouro-Djiama, Tepare, and Bognori close to Mansila, killing at least 100 people.[4] The first convoy reached Mansila on May 4, returning via a slightly different route.
The second convoy was composed of soldiers from BIRs 20, 12, 4, and 19, and left Fada N'gourma between May 3 and 5 towards Tankaoulou and Foutouri before returning to Fada N'gourma on May 19.[4] The second convoy did not encounter any jihadist attacks, and only discovered one explosive mine. Despite this, Burkinabe soldiers opened fire in several villages they came across, not distinguishing between men, women, or children.[4] Survivors noted that a predominantly Gourmantche village was spared, but Fulani villages were decimated. The villagers targeted admitted to paying a JNIM-enforced zakat tax, which the military took as proof of the villagers' collusion with JNIM.[4] Around 100 people were killed between May 3 and 9 in villages on the road between Tankaoulou and Fada N'gourma.[6]
Several casualties were reported from at least five mine explosions that the first convoy ran across. The villages that were hit the worst by the massacres were Gatougou, where 84 people were killed and photos showed the bodies of at least seventy people littering the streets of the locality, including women and six infants; Reports from Kampalougou estimated that at least 79 people were killed later on in the convoy's journey. Videos, some taken by the soldiers and some by jihadists who were the first to arrive on scene after the massacres, showed corpses of men, women, and children, including burned bodies.[7]
