Residents of Maiduguri, the Borno state capital, reported hearing multiple explosions Tuesday evening.
It is not yet clear what led to the blasts, but residents said that it started around 6pm.
“I was on my way to the mosque when I started hearing the sounds of the bomb blast, followed by that of gunshots,” one of the residents told TheCable.
“The sounds were coming from Gwange area of the town,” he added.
Another resident expressed fear that it might be an attack from suspected Boko Haram insurgents.
“What I hear is that the insurgents are trying to come into town through Meri village, close to the University of Maiduguri,” he said.
