The religious conflict is Nigeria is a very serious one, and it brings in lot of instability, violence, death, in the country. The reason why this happens is mainly because big portion of the population is uneducated, so the religious authorities that very often are extremists, use that and control the people with ease in order to satisfy their own twisted ideologies.
The fact that the Christians and the Muslims have traditionally had conflicts with each other, preaching hatred towards the other religious groups, and open call for violence, had made a mess of the country, and unfortunately it doesn't seem that the government has a solution for the situation.
