Soldiers have moved in to halt a confrontation between Christians and Muslims at a cemetery near the city of Jos, where religious tensions are high.
Christians were trying to stop Muslims from burying a dead child in the Naraguta area.
The cemetery is claimed by both Muslims and Christians and the ownership is the subject of a court case.
More than 300 people died last month during days of rioting in Jos between the two religious groups.
Thousands of police and military personnel were deployed to control the violence.
The BBC’s Ahmed Idris, in Abuja, says there is still a huge deployment of security forces in the area and tensions between the two communities remain high.
There were reports of stone-throwing and several arrests during the disturbances in Naraguta, which is 15km (9.3 miles) from Jos.
Muslims claim that the land they are now using as a cemetery was sold to them by Christians.
But Christian groups deny this and say they still own the land.
Jos, the capital of Plateau state, lies between Nigeria’s mainly Muslim north and predominantly Christian south and has seen several outbreaks of sectarian violence in the recent past.
But analysts say the real cause of the violence is a struggle for political superiority in the city.
