He extended his condolences to families of the victims, assuring them that the government would do everything within its power to track down those responsible.
It was a bloody Sunday morning in Ozubulu in Ekwusigo Local Government Area of Anambra state, as a lone gunman stormed a Catholic Church in the area mowing down no less than 8 worshipers.
The first person to be killed in the church was the father of one of the alleged drug lords, said another resident, Abel Amansi.
He said the gunmen then went on rampage and "shot at the remaining worshippers numbering over 100".
A witness, who simply identified herself as a choir member, said that the church was dark as there was no light.
"So far, 12 persons have been confirmed dead and deposited in the mortuary here while several persons are receiving medical attention", a staff worker at Nnamdi Azikiwe University Teaching Hospital in Nnewi, where the victims were admitted, told AFP.
