Rescue workers say 45 people died and they have rescued 105 survivors from a collapsed guesthouse at the campus of renowned Nigerian preacher T.B. Joshua's Synagogue Church of All Nations.

Joshua is broadcasting a video purporting to show a plane flying low over the building four times before it collapses on Friday. He says the building was attacked by Islamic extremists using an aircraft. It is on the outskirts of Lagos, Nigeria's commercial capital in the southwest.

National Emergency Management Agency spokesman Ibrahim Farinloye said Monday the collapse likely was caused by construction to add two stories to the four-story structure without any fortification of the foundations.

He said church members initially tried to impede rescue workers but that the search continued Monday for more bodies and survivors.
