The world’s deadliest terrorist group is not in the Middle East, but in Nigeria, where the Islamist insurgency Boko Haram and other forces killed more than 4,000 Christians in 2015 - a 62% increase from 2014. In response, Nigeria's largest confederation of Christian churches is, for the first time, jointly endorsing a commitment to revive the Church in the country's north, before it collapses from a decade of violence that has killed thousands of Christians and driven away more than a million. Christians in the northern region have for long been abandoned to their own fate by the Nigerian authorities. ‘This is the first time we’re going public to sign a declaration which gives the true picture of the persecution Christians are going through in this country,’ said Rev Musa Asake.
