Operations still under way in bid to retake territory in northern Yatenga province
Seventeen soldiers and 36 volunteer fighters have been killed in heavy clashes with militants in northern Burkina Faso, the army has said. It is the worst attack in months in the west African country that has been fighting hardline militants for years.
Burkina Faso has been battling armed groups, some with links to al-Qaida and Islamic State, in its northern desert region since 2015.
