On Saturday, the Army repelled further attacks by the Islamic State of the West African Province (ISWAP) in at least three areas of the local government of Borno State.
Terrorists attacked local government areas of Monguno, Ngazai and Gubio almost simultaneously at noon, firing sporadically.
Soldiers returned fire, involving the invaders for a long time.
The terrorists abandoned the fight in the face of the superior fire of the troops.
Thousands of internally displaced people living in the city are said to have fled for safety.
Boko Haram terrorists, in another attack on Wednesday, killed more than 70 people in the village of Faduma Kolomdi, in the local government area of Gubio.
The insurgents, who entered the village in trucks and motorcycles, also took many cattle.
