The attackers targeted several villages located on the borders of the local government areas of Mangu and Barkin Ladi, said Joseph Gwankat, head of the Mwaghavul Development Association, or MDA.

Survivors reported that gunmen indiscriminately shot at people, including women and children, and set fire to houses and property.

James Bot, survived one of the attacks.

"Yesterday now, when we are in the hospital we heard voices in the morning, they came out to burn one church opposite the hospital. They were able to set fire but people came out and extinguished the fire. They came back again and we extinguished the fire, and they came back again the third time but they were not able to succeed.''

The latest violence on Tuesday and Wednesday came after a Christmas Day attack in the area which left at least 140 people dead.

A dusk-to-dawn curfew was imposed on January 23.

The MDA said in a statement that it blamed the attack on herders, and questioned why troops deployed by the federal government to the area didn't intervene.

A Nigerian defense spokesperson said the military remains neutral following allegations of partisanship in the conflict, adding that troops responded professionally.

The latest attacks come amid a surge in violence in the Plateau, which has seen repeated clashes between nomadic herders and local farming communities.

Violence in central Nigeria has claimed hundreds of lives in recent years.
