Lt-Col Mohammed Dole, the new military spokesman, said the operations which involved ground and aerial assault by the Air Force destroyed identified terrorist camps, killing 74 suspected militants, while others fled with serious injuries.
Two Isuzu tiger pick-up vehicle and five Hilux belonging to the militants were destroyed, he added.
In another operation, the 3 Division Special Operation Battalion in Damaturu, the Yobe state capital, confirmed Friday the killing of 21 insurgents in the state.
A statement signed by Captain Eli Lazarus, spokesman of the battalion, said the insurgents were killed Thursday, while some weapons and ammunition were recovered during the operation.
He said the insurgents attacked a military check point close to the NNPC mega petrol station on Damaturu-Maiduguri road.
A 24-hour curfew was imposed across the state to enable troops pursue the fleeing terrorists. Damaturu streets had remained empty with all business premises closed as residents stayed indoors.
Boko Haram has caused thousands of casualties in Nigeria's northern states since 2009.
In the escalation of conflicts between its fighters and the military, Nigerian President Goodluck Jonathan declared in May a state of emergency in the northern states of Adamawa, Borno and Yobe.
In April, the Nigerian government tried to broker a ceasefire with the group but failed.
