The attack happened hours after President Muhammadu Buhari paid a condolence visit to the people of the state over the killing of 30 persons on Sunday.
A resident told TheCable that the insurgents have been shooting sporadically for over 30 minutes.
“We are under serious attack right now. Boko Haram stormed the town hours after the president left,” he said.
Buhari had headed to Borno from Ethiopia where he attended the African Union summit.
Speaking at the palace of Abubakar Elkanemi, the shehu of Borno, the president had said Boko Haram could not thrive without local support.
“This Boko Haram or whatever they are, cannot come up to Maiduguri or environs without the local leadership knowing because traditionally the local leadership is in charge of security in their own respective areas. So with my understanding of our culture, I wonder how Boko Haram survives up till now,” he had said.
Boko Haram has continue to inflict hardship on residents of north-eastern states, despite efforts of the government to put the group in check.
The frequency of the attacks made federal lawmakers and some Nigerians to demand the removal of service chiefs.
But in an interview with TheCable and THISDAY/ARISE, Tukur Buratai, chief of army staff, said Buhari should not be pushed into sacking his service chiefs.
“I am tempted not to comment on this particular issue because I am directly involved. However, I want to believe that whatever happens, the commander-in-chief is the right arbiter, and he knows where it pinches, he knows where the problems are. I think the decision should be left to him. He should not be pushed or prompted in this regard,” he had said.
