At least 35 civilians were killed and 37 were injured in northern Burkina Faso on Monday, when a vehicle in a convoy hit an improvised explosive device (IED), the interim government said in a statement.
The escorted supply convoy heading to the capital of Ouagadougou hit the IED between the northern towns of Djibo and Bourzanga, an area where Islamist militants have escalated attacks on villages, police and military outposts since 2015.
"Escorts rapidly secured the perimeter and took measures to assist the victims," the military government said in a statement.
Insecurity has risen across West Africa's Sahel over the past decade as groups with links to al-Qaida and Islamic State have gained ground, killing thousands and displacing more than a million people despite the presence of foreign troops and United Nations peacekeepers.
Frustrations about spiraling attacks spurred a military coup against Burkina Faso's ex-President Roch Kabore in January.
But levels of violence have remained high.
Nearly one in 10 people in Burkina Faso has been displaced by conflict and severe food insecurity has almost doubled compared to 2021 as fields and livestock are abandoned, according to the Norwegian Refugee Council.
