Authorities in central Nigeria say at least 11 people were killed in a recent resurgence of ethnic and religious violence in the region.

The latest attacks occurred overnight Sunday near the central city of Jos in Plateau state.

Officials say at least seven people were killed in an attack in the Babale area, while four people were killed in an attack in Dabwak village, located south of the city. On Saturday, eight members of the same family were killed in an overnight attack.

Jos sits in a region known as Nigeria's “Middle Belt” that separates the mostly Christian south from the predominantly Muslim north. Thousands of people in Plateau have died in sectarian violence over the past decade.

Much of the regional tension comes from land disputes between mostly-Christian farmers and predominantly-Muslim herders.
