Suspected Fulani militias have engaged in gun duel troops of the Nigerian Army in Jenabbai, around Nukkai, in Jalingo, the Taraba state capital.
Local sources said they have fled the area for fear of being caught in the crossfire.
There was no immediate explanation as to the cause of the violence.
SaharaReporters reports that the situation in the area has always been volatile.
Last Sunday, four people were reportedly killed in a similar invasion of communities around the same area, just as David Misal, the Police Public Relations Officer (PPRO) assured that calm had retuned in the area.
