The Nigeria state of Adamawa has declared an around-the-clock curfew after a wave of deadly attacks targeting Christians have left 30 people dead.
The militant Islamist group 'Boko Haram', which carried out the attacks, has vowed to kill Christians if they do not leave the predominately Muslim north.
The Islamist group has killed more than 500 people in the past year.
The Head of Nigeria's Christian Community Pastor Ayo Oritsejafor called on the country to unite against the attacks.
Pastor Oritsejafor said that deadly attacks on churches and faithful suggest "religious cleansing" and compared the violence to the run-up to the 1960s civil war.
The stark warning in Africa's most populous nation and largest oil producer comes with at least six gun and bomb attacks targeting Christians since Christmas having killed more than 80 people.
