A Boko Haram commander, Abu Imrana, has been killed in a gun battle with Nigerian soldiers in Borno state, a security source told the Cable on Monday.
Imrana is among the insurgents who fell to the superior firepower of the military in the Marte area of Borno state, the source said.
He is said to have coordinated the killing of at least 150 people across Monguno and Gubio local government areas of Borno last week.
A soldier and a policeman who were captured two weeks ago were killed publicly by the group.
Recently, Boko Haram renewed its attacks on military formations and north-east communities amid claim by President Muhammadu Buhari, in a democracy day broadcast, that the terror group has been downgraded.
