In a separate attack carried out on Tuesday, militants gunned down 48 men after they had finished prayers in two villages near the town of Monguno, a resident said. The town had recently been captured by the terrorist group.
At least 17,000 people, mostly civilians, have been killed since 2009, when Boko Haram launched a deadly offensive to try to impose militant Islamist rule, according to Amnesty International.
