A spate of attacks on towns and villages in Nigeria's Borno State has left at least 150 people dead since Tuesday; some witnesses claim 200 people were killed in the attacks.
According to reports, Boko Haram militants launched raids which targeted worshippers as they finished prayers, and shot villagers who were in their homes. The group also torched houses and laid mines in the aftermath of the attacks.
On Friday, Nigerian President Muhammadu Buhari condemned the attacks as "inhuman and barbaric." Buhari took office after winning elections in March, when he pledged to "spare no effort" to defeat Boko Haram.
