Bandits allegedly engaged the military in a gunfight at a checkpoint in Zuma Rock Madalla, along the Kaduna-Abuja highway, on Thursday evening.
It is unclear whether there were any casualties.
According to multiple sources, the incident caused a traffic jam on the highway.
According to an eyewitness, the attack began around 8 p.m.
The police and military were not immediately available to comment on the incident.
This latest attack on a military installation comes just days after bandits killed at least three soldiers when they attacked a unit of the presidential brigade guards.
