At least 19 members of Burkina Faso's army were killed in an attack in the north of the country on Monday, two security sources said, the second major assault on forces fighting jihadist militants in the area in less than a week.
The West African nation has become a hotspot for attacks by insurgents linked to al Qaeda and Islamic State, who have seized territory across the Sahel region south of the Sahara over the past decade, killing thousands and displacing millions despite the presence of foreign troops and United Nations peacekeepers.
The latest attack targeted a military camp in the town of Tin-Akoff in Burkina Faso's Oudalan province, less than 100 km from where at least 51 soldiers were killed in an ambush on Friday - one of the heaviest death tolls in recent memory.
