BBC: At least 70 lecturers from the University of Maiduguri have resigned since 2009 when militant Islamist group Boko Haram began terrorising residents in the north-eastern Nigeria city.
The number of students enrolling has dropped significantly since the insurgency started in Maiduguri, the former headquarters of Boko Haram, says Dani Mamman, union chairman for the university’s academic staff.
He also told the BBC that the university has employed lecturers to replace those who left.
The university has recently been targeted by suicide bombers, most of whom are young women.
In July, authorities in Borno state began digging a 27km (17 miles) trench around the university to prevent attacks by militants.
They took action a day after three suicide bombers attacked the university, killing themselves and a security guard.
