Lagos - A rescue operation was underway in Lagos on Friday after a building linked to a Nigerian preacher's megachurch collapsed, the country's emergency relief agency said.
The National Emergency Management Agency (NEMA) said the building -- a guesthouse for foreign members of preacher TB Joshua's The Synagogue Church of All nations -- came down in the Ikotun area of the city.
"We are on the way to the scene and have no further details," NEMA's southwest coordinator Ibrahim Farinloye told AFP by telephone.
There was no immediate official confirmation on casualties.
TB Joshua, dubbed "The Prophet", is one of Nigeria's most famous preachers and televangelists with thousands of followers across the world, attracted by his purported healing powers and prophecies.
According to his website, his church "hosts thousands of national and international visitors" every year.
"People travel from around the world to witness and receive from the mighty work that God is doing in the life of Prophet TB Joshua," it states.
