Police in Nigeria’s central Plateau state said on Tuesday that 20 people had been killed in a weekend attack on a community in Bokkos district, the latest in a region plagued by communal attacks, despite repeated security deployments and government vows to stem the attacks.Plateau is one of several ethnically and religiously diverse hinterland states known as the Middle Belt, where communal conflict has claimed hundreds of lives in recent years.Plateau police spokesperson Alfred Alabo said officers, working with other security agencies, engaged the attackers in a “fierce gun battle” early morning on Sunday before they fled.Eighteen people were killed at the scene, and two died later in the hospital, Alabo said.Plateau police commissioner Bassey Ewah has ordered additional deployments to the area, including more tactical and mobile police units, Alabo said.
