Unidentified gunmen on Sunday attacked St. Francis Catholic Church in Owo, Ondo State, killing many members of the congregation.
Though the mission of the gunmen was not known, they also bombed the church.
A video sighted by our correspondent showed a gory scene of dead bodies with blood gushing out freely from their bodies.
Owo is the hometown of Governor Rotimi Akeredolu.
A message sent to the Commissioner for Information, Donald Ojogo, was not responded to.
