Suspected Boko Haram militants attacked two military locations around the fringes of Sambisa forest early Sunday morning.
The first attack on troops of 26 and 28 Task Force Brigades was repelled after a 16-hour battle.
16 Boko Haram militants were killed.
A statement from the director army public relations, Brig. Gen. Sani Usman, said the daring attack by fleeing Boko Haram terrorists occurred at Pulka and Bitta the former Boko Haram Caliphate in Gwoza local government area of Borno state.
According to the statement, the second attack was on troops of 114 Task Force Battalion.
“The troops came under three-pronged attack by Boko Haram terrorists fanning out of Sambisa forest from Damboa, Tokumbere and Pulka axis.
“At the end of the debacle, 2 Boko Haram insurgents paid for their atrocities with their lives while several others sustained gun shot injuries.
“The fate that befell those that attacked Pulka was more dreadful.
“The ever ready and vigilant troops rose to the occasion by repelling the attacks and killing all the 16 attackers and captured one of them alive during the exploitation.
“The gallant troops also recovered 11 AK-47 rifles, 3 General Purpose Machine Guns (GPMGs), 1 Browning Machine Gun (BMG) and 2 Toyota Hilux vehicles.
“Others are a 60mm Mortar tube, 7 boxes of 12.7mm ammunition and 1 belt of 12.7mm ammunition.
“It is gratifying to state that there were no casualty on our own troops except for 3 soldiers that sustained minor injuries.
“The troops remained on maximum alert and are equally busy consolidating and continuing with their clearance operations with high morale”, the statement said.
