The UN says at least 110 Civilians have been killed and many injured in attacks on two villages in northeast Nigeria. No one has claimed responsibility for the attack. but the armed group Boko Haram has carried out a series of deadly assaults in the area in recent years. Security forces are looking for dozens more villagers who are missing, many of them women. It is the worst attack on civilians in Borno state this year. President Muhammadu Buhari claimed five years ago that Boko Haram had been defeated.
