Commissioner of Police Damien Chukwu while briefing newsmen in his office Monday said it took the grace of God for the suicide bombers not to unleash their planned terror on the various Eid grounds in the state.
He said that a female suicide bomber entered the university premises and detonated her explosives, killing herself and injuring three security personnel.
He added one of the injured security personnel later died.
Four female suicide bombers then killed eight people around an hour later on the outskirts of the city in Zannari community, after detonating devices in residential buildings.
"In all, sixteen persons including the suicide bombers died in the multiple explosions while thirteen persons were injured", Chukwu stated. "But the third suicide bomber amongst the suspects only killed herself, by detonating the IED strapped to her body without hitting any target", he said.
The CP said some 13 other persons were also injured as a result of the bomb attacks.
One of them was said to have been detonated close to the Entrepreneurship and Skill Acquisition Centre Complex, while the other was behind the Works Department complex.
According to him, EOD/SARS and patrol teams were mobilised to the scenes as the dead and injured were evacuated to University of Maiduguri Teaching Hospital.
