Scores of people have died when a church building collapsed in Nigeria. It is reported that the roof of the church, Reigners Bible Church, caved in on worshippers who had gathered for the ordination of a bishop. Some witnesses have told the media that the church was still under construction and workers had rushed to complete it for the ordination. In 2014, a guesthouse belonging to preacher T.B. Joshua's church collapsed in Nigeria's main city of Lagos, killing at least 115 people, 84 of them South Africans. We are joined on the line by our correspondent in Nigeria Sophia Adengo
