On September 26, a supply convoy bound for the town of Djibo, the capital of the Sahel region in the north of the country, was attacked by gunmen.
In a statement posted on social media and authenticated by the U.S. SITE jihadist monitoring center, the al-Qaeda-affiliated Islamic and Muslim Support Group (GSIM) claimed responsibility for the ambush.
The army-escorted convoys supply northern towns under blockade by jihadist groups that have recently blown up bridges on major highways.
The town of Djibo, which had not seen a road supply convoy arrive for some 40 days, according to the transporters' union, was supplied by helicopter on Tuesday with 70 tons of food, according to the army.
Burkina Faso was the scene of a putsch on Friday, eight months after a first coup.
Captain Ibrahim Traoré, the new strongman of Burkina Faso, overthrew Lieutenant Colonel Paul-Henri Sandaogo Damiba, blaming him in particular for the lack of results in the fight against jihadists.
Since 2015, regular attacks by armed movements affiliated with al-Qaeda and the Islamic State (IS) group have killed thousands and displaced some two million people.
