The Secretary-General of the Miyetti Allah Cattle Breeders Association of Nigeria (MACBAN), Usman Baba-Ngelzerma, said 40 corpses were recovered from the site of the bomb attack in the village of Rukubi in the Doma Local Government Area of the north-central state.

"The people involved in the incident are 40. A total of 40 died as a result of the bomb," Baba-Ngelzerma told a local TV station.

Some members of MACBAN had blamed a military airstrike for the incident.
