Police in Burkina Faso say four people have been killed in an ambush on a police patrol in the north of the country.
Three of the dead were police officers. Another five people were injured.
Monday’s attack happened on the Pissila-Gibga axis of the Sanmatenga province in Centre-Nord Region, northeast of Burkina Faso.
Last Tuesday three soldiers were killed in a region near the Mali border.
Like Mali and Niger, Burkina Faso is caught up in an Islamist insurgency in which more than four thousand people died last year.
