Two suicide bombers exploded their vests at the Maiduguri University in Nigeria’s Borno state, the birthplace of the Boko Haram terror group.
A professor and a child were killed and at least 17 other people wounded in the northeastern city.
Police shot a third suicide bomber, a child, about 12 years old setting off her vest. It is the first time that a university has been attacked.
Boko Haram has not claimed any responsibility but it is mainly the only terrorist group carrying out attacks in northern Nigeria. Since the insurgency started seven years ago, more than 15,000 people have been killed.
At least three soldiers and 10 Boko Haram fighters were killed when the insurgents attacked an outlying army post in northern Borno state last week.
The attack is the first major attack since Buhari last month declared that Boko Haram was “crushed.” Boko Haram was last month pushed out of the Sambisa forest, where it hand its camps, but the group has bases across borders in neighboring countries.
Nigeria’s army said Sunday that troops continuing “clearance operations of remnants and fleeing Boko Haram terrorists” killed several insurgents and rescued 58 kidnap victims, mainly women and children last week. One soldier was injured, it said.
