Troops of the Operation Hadin Kai have intercepted a vehicle carrying N37 million suspected to be linked to terrorist financing in Borno State.
The operation was conducted by the Joint Task Force North East under ongoing counterinsurgency efforts.
Military authorities said the vehicle was stopped during routine patrol along a known terrorist transit corridor.
Five occupants were arrested, while several mobile phones were recovered for further investigation.
Spokesman Lieutenant-Colonel Sani Uba described the seizure as a breakthrough against insurgent logistics networks.
He said the action forms part of a broader strategy to disrupt financial channels supporting terrorist operations.
In a related development, troops repelled coordinated attacks on Pulka and Mandaragirau communities in Gwoza Local Government Area.
During the confrontation, a senior commander of Boko Haram identified as Abou Aisha was killed.
The commander reportedly sustained fatal gunshot wounds during intense exchanges of fire.
Security forces also recovered weapons and other equipment from the fleeing insurgents.
The attacks were launched from the Sambisa Forest axis between February 14 and 16, according to the military.
Troops responded with sustained firepower, forcing the assailants to retreat.
Military authorities confirmed no fatalities among soldiers during the engagements.
However, some members of the Civilian Joint Task Force supporting the troops lost their lives.
Injured personnel were evacuated through the Air Component of Operation Hadin Kai and Nigerian Army aviation units.
The military said operations would continue to deny insurgents freedom of movement across the theatre.
