Violence broke out after Nigerians re-elected as president a Christian from the south over a Muslim from the north.
More than 100 people were reported dead and at least 10 churches and one police station were burned.
Following the April 18 announcement of President Goodluck Jonathan's victory, Christian and Muslim leaders united to condemn the violence in a country divided along religious lines.
Christian Solidarity Worldwide also reported a number of attacks on mosques.
