Unconfirmed reports out of Jos are indicating that a huge explosion a few minutes ago took place at a Catholic Church in the city.
Eyewitnesses said that St. Finbars Catholic Church in the Rayfield area of the Plateau State capital was the target.
One witness said he and his family heard a huge explosion in the area as they made their way home from another church.
However, National Emergency Management Agency (NEMA), officials who confirmed the bomb blast said there were 'numerous casualties'.
"NEMA officials are on the scene of a suspected suicide explosion at Finber's Catholic Church, Rayfield, Jos. They are about to evacuate victims to hospital," NEMA spokesman, Yushau Shuaib told Reuters.
This is the second time in recent weeks that a church has been targeted in Jos.
On the 26th of February a bomb targeted the headquarters of the Church of Christ in Nigeria destroying a number of cars and killing the bomber in the process.
The Boko Haram, a radical Islamic group operating in northern Nigeria has claimed responsibility for several deadly bomb blasts in country.
Styled on the Taliban, it has become increasingly sophisticated and deadly in its methods in the past six months and widened its targets beyond attacks on police and other authority figures to include Christians.
