Officials in Burkina Faso said on Sunday that four people had been killed in an ambush, including the deputy mayor of the northern town of Djibo.

The governor of the Sahel region said unidentified armed men ambushed the deputy mayor's vehicle in the commune of Gaskindé.

It is the latest in a series of attacks in the north of Burkina Faso, where hundreds of people have been killed in a jihadist revolt.
