Gunfire and explosions shook a town in Borno State, northeast Nigeria on Tuesday, residents have said.
Clashes broke out in the town of Gamboru Ngala on the border with Cameroon on Monday night and continued on Tuesday, a resident said. The military had not commented on the situation there and details remained unclear.
Gamboru Ngala is the headquarters of the Ngala local government area of Borno State.
The situations in the two towns did not appear to be linked as they are located hundreds of kilometres apart.
In Gamboru Ngala, one resident told AFP the fighting began after someone who runs errands for immigration officers was shot and wounded.
“We have been bombarded with explosions and sounds of gunfire since yesterday evening,” the resident told AFP.
Residents over the border in Cameroon also reported hearing gunshots.
