Another suicide bomb attack occurred in the University of Maiduguri, UNIMAID, less than 48 hours after three suicide bombers attacked the same institution.

Security operatives say the suicide bomber detonated his explosive outside the perimeter fencing of the school on Saturday morning.

Borno State police commissioner, Damian Chukwu, said the incident happened at about 10 a.m, adding that the attacker hid near the university’s Children Secondary School.

He was said to have detonated the bomb when he sighted a security man coming in his direction.

There was no other casualty in the incident, he said.

The incident, the third in less than two weeks, has increased fears in the school environment with students and staff members expressing worry over the frequency of the attacks.

UNIMAID was first attacked in January this year.

A professor of veterinary medicine and a little child were among the casualties in the attack that occurred at a mosque in the university premises.

Though there had been series of suicide bomb attacks in Borno State by mostly female teenagers recently, some Nigerians wonder whether the upsurge in the attacks has anything to do with the recent threat by the Boko Haram.

It would be recalled that last week, one of the Boko Haram commanders swapped for the 82 abducted Chibok School girls, Shuaibu Moni, appeared in a video which was released on the internet, threatening more attacks, including in the Federal Capital Territory, Abuja.

However military authorities dismissed the video as “cheap propaganda”, assuring Nigerians that there was nothing to worry about.
