At least, 96 people were killed in Benue State when several villages were attacked by suspected Fulani herdsmen, a state police spokesman and an army source said on Tuesday.
Hundreds are killed each year in clashes pitting the semi-nomadic, cattle-herding Fulani people against more settled communities that practice a mix of farming and cattle rearing. The clashes are always driven by disputes centred on land use.
A senior military officer said fighting around five villages lasted several days in the Logo Local Government Area of Benue.
Police spokesman, Austine Ezeani, said a mobile police unit was deployed in the area.
The unrest is often seen as sectarian in nature since Fulani are Muslim and the communities with which they are in conflict in the Central Nigeria tend to be Christian.
Nigerian troops fought militiamen in early May, after dozens were killed in villages on the border of middle belt states, Plateau and Taraba.
