No group immediately took responsibility for the attack. However, Boko Haram and its Islamic State faction, ISWAP, are active in the area.

Nigeria has been waging a war against Boko Haram since 2009. The terrorist sect craves a hard-line Islamic state from the northeastern region of Nigeria.

More than 50,000 people have been killed, millions have been displaced and thousands held hostage by the terrorists since the conflict began.

President Buhari and army chief Tukur Buratai have often boasted that the sect has been technically defeated, even though Boko Haram is still capable of mounting soft target attacks and abducting civilians.
