More than 200 people are dead in attacks on Christian villages in central Nigeria. It's the latest round of violence between Christians and Muslims.
Witnesses said a mob armed with guns and machetes entered a village around 3 a.m. Sunday, at a time when the military should have been guarding the area.

Most of the victims are said to be women and children. Those who escaped say the attackers were Muslims.
"[We will] undertake strategic initiatives to confront and defeat these roving bands of killers," acting President Goodluck Jonathan said in a statement. "While it is too early to state categorically what is responsible for this renewed wave of violence, we want to inform Nigerians that the security services are on top of the situation."
More than 300 people -- most of them Muslims -- have died in religious riots in Nigeria in January.
More than 600 people fled to a makeshift camp that still held victims from January's violence, said Red Cross official Adamu Abubakar.
