The authorities in Burkina Faso say nine members of the military and at least 10 civilians have been killed in an attack in the northern city of Foubé.
Last week around 50 soldiers died during another raid in the north.
Anger is growing in Burkina Faso over the extremist violence that’s killed thousands and displaced more than a million people since 2017.
There have been protests and calls for President Roch Kaboré to resign.
