The attack came after the General Officer Commanding 7 Division of the Nigerian Army, Brigadier General Victor Ezugwu, spent Tuesday night with troops during an operational visit.
His convoy was ambushed on Tuesday on its way to Bama. One soldier was killed while two other sustained injuries in the attack.
No group has claimed responsibility for the attack, but the Boko Haram is largely suspected. The terrorist group has carried out such attacks in the region in the past.
