Nigerian forces seized an arms cache as well as ammunition from a Boko Haram terrorist camp in the country's volatile northeast.
Army Media Coordinator Aminu Iliyasu said in a statement that Nigerian and Chadian troops launched an offensive against Boko Haram around the country's Lake Chad region.
"Troops have recovered an additional four AK 47 Riffles, one Rocket Propelled Gun (RPG) Tube, one 60mm Commando Mortar, one abandoned Gun Truck and one motorcycle belonging to the fleeing Boko Haram," he said.
Iliyasu said troops "successfully repelled" a Boko Haram attack on a military base in the town of Gubio, Borno State near Lake Chad.
He said additional weapons and equipment were recovered from the terrorists during the gun battle.
The fresh military offensive against Boko Haram came after nearly five months of renewed attacks on army deployments and civilians in the area.
At least 20 military personnel have been killed over the last five months during attacks by Boko Haram, amid a decade of violence and terror attacks in the country's northeast region.
