On 26 September a civilian convoy accompanied by a military escort sought to resupply the besieged city of Djibo in northern Burkina Faso.
Access routes into the city have been controlled by Al-Qaeda linked militant group Jama’at Nasr al-Islam wal Muslimin (JNIM) since the beginning of 2022, causing thousands of people to become food-insecure and leaving the city’s inhabitants dependent on escorted convoys and air drops for food and medicine.
However, when the convoy reached within 25 kilometres of Djibo, it was ambushed and at least 27 soldiers and 10 civilians were killed. The JNIM claimed responsibility for the attack and posted footage on social media that allegedly showed the incident and its aftermath.
The Burkinabè army was accompanying the convoy when it was attacked. Several days after the ambush military commander Ibrahim Traoré staged a coup and took control of the country and pledged to improve the security situation.
Using satellite imagery Bellingcat has counted 95 vehicles destroyed in the convoy attack, stretching across more than five kilometres of highway. Combining it with footage, we were also able to geolocate a number of the destroyed vehicles on the highway.
The ambush reportedly took place in a remote area on the N22 road near the town of Gaskindé in the country’s Sahel Region.
A truck driver who survived the attack told France 24 that he initially hid under his truck when the shooting started, but then the vehicles began to catch fire.
In the footage posted by JNIM, dozens of burnt out trucks can be seen along a road.
However, geolocating the vehicles in the footage was tricky because of the limited number of distinguishing features in the semi-arid, rural landscape.
After Héni Nsaibia, a researcher for ACLED and Menastream, contacted Bellingcat asking if we had access to satellite images that could show the remains of the vehicles, Bellingcat sought to gauge whether such imagery could provide further details.
A Sentinel-2 image taken five weeks after the attack showed there was significant discolouration on a stretch of the N22 that could be the remains of vehicles, at coordinates 13.899898477602783, -1.654384743523484.

Notice the black marks in the October 31 image that were not there at 10:47am on September 26.
With the hypothesis that this was where the convoy was attacked in mind, we tasked a Planet satellite to see if we could obtain more detailed images of the area.
Not only did the Planet image show that our hypothesis was correct, it allowed us to verify the video posted by JNIM and confirm it was shot at the scene of the September 26 ambush.
Using satellite imagery from Planet Labs, Bellingcat located the remains of the convoy scattered along the highway.
The extent of damage was still clearly visible in the satellite imagery, taken five weeks after the attack.
This allowed us to count the number of destroyed vehicles left on the road.
We were able to identify some of the burnt out vehicles visible in the satellite image and footage based on how they were positioned near each other on the road.
For example, the vehicles in the black and orange boxes are located in the middle of the burned out convoy.
Distinctive marks behind a burned out vehicle were still visible in the satellite image and could be matched to the footage.
At the back of the convoy two vehicles, also seen in the video, are positioned beside each other. One of these vehicles appears to have partly fallen off the road.
In total, Bellingcat counted 95 vehicles scattered along the highway.
It must be noted that it was not possible to match all 95 vehicles that we counted using the satellite imagery with the vehicles in the footage.
The footage featured a number of jump cuts and did not film continuously along the whole five kilometre stretch of highway.
However, the satellite imagery does show the scale of the attack, which is hard to grasp with footage alone.
For a richer explanation of how we matched video and satellite imagery see the drop down box below.
Identifying the Vehicles
The vehicles in the footage were identified in clusters; the vehicles were filmed south to north along the road (starting at the back of the convoy and driving north).
The vehicles in the black and orange boxes (numbers 49 and 50 on the Planet image) are located in the middle of the burned out convoy. Although there is little vegetation in the area, the vehicle in the black box can be identified as it is located next to a small bush and in front and to the side of the vehicle in the orange box. This matches the footage of a distinctive blue vehicle seen next to a small bush.
Further down the road, there is a vehicle at a very slight angle (pink box) followed by one perpendicular to the road (red box) and then a longer vehicle further ahead (blue box). Together these vehicles (numbers 65, 64 and 63 on the Planet image) form a cluster that can be identified in the footage and matched to the vehicles on the road in the satellite image.
The vehicle in the turquoise box is positioned behind and to the side of the vehicle in the yellow box (number 70 and 69 on the Planet image), they can be identified along with the next vehicle (orange box).
The distinctive marks behind the burned out vehicle (number 71 on the Planet image) were also still visible in the satellite image.
The remains of the same vehicle can be seen alongside a small bush to the side of the road (green box).
The cluster of vehicles can be seen here in the footage.
In this cluster (numbers 79,78 and 77 on the Planet image) three vehicles can be seen in the footage. Two (in the green and red boxes) are roughly perpendicular to the road with one vehicle (turquoise box) in between them. Few vehicles were positioned in the same way which made it easy to identify.
Since the convoy attack, humanitarian groups working in Djibo have warned that conditions in the city have continued to deteriorate with ongoing shortages of food and medicine and Burkina Faso has continued to struggle with insecurity in the Sahel Region.
Almost a month after the attack on the convoy JNIM claimed responsibility for another attack in the area; an army base on the outskirts of Djibo which killed at least 10 soldiers and injured dozens.
