At least 96 people have been killed in Nigeria after several villages were attacked by nomadic herders in a land dispute.
The massacre took place in the province of Benue, near the country's middle belt region, and is suspected to have been carried out by Fulani herdsmen.
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 to the area.
Nigerian troops fought militiamen in early May after dozens were killed in villages on the border of middle belt states Plateau and Taraba.
The first sign that one is entering Boko Haram's self-declared "caliphate" in north-east Nigeria is that there are no signs. All around the town of Michika, which fell to the sect in September, gunmen have daubed black paint over signs written in English, be it advertising a local church or simply giving directions to the next town.
With their roots in South Africa apartheid-era security forces, they do not fit the standard image of an army of liberation. But after just three months on the ground, a squad of grizzled, ageing white mercenaries have helped to end Boko Haram's six-long year reign of terror in northern Nigeria.
