Nigeria is known to be the deadliest place for Christians to live out of all other foreign countries. In one incident, two Christians were beaten until the attackers thought the victims were dead. These attackers were Muslim Extremists who said they were just following the Islamic law. Many Christians flock to the Southern part of Nigeria where it is less aggressive because in the North, the Muslims are in complete control of government affairs. In one terrifying incident, four people were killed and two churches were trashed. The robbers tore out pews from these churches and burned them for the whole Muslim community to see.
