Nigeria: Army gives villagers ultimatum

Nigeria's army has warned thousands of Plateau state residents to leave their homes as it begins an operation against those accused of a recent spate of deadly attacks. Some 100 people were killed recently after attacks on villages inhabited by Christian ethnic groups. Two senior politicians then died after gunmen opened fire at a funeral for some of the dead. Reports say thousands of Muslims are refusing to leave. Plateau state straddles the dividing line between the mainly Muslim north of Nigeria and its largely Christian and animist south.
