Thirty-seven people were reportedly killed in Kajuru Local Government Area of Kaduna State by gunmen.
The incident came barely three days after four herdsmen were said to have been killed by gunmen in the same place.
The fresh round of violence is said to have erupted, between farmers and herders, leaving many other people injured in Kajuru which is about 50km from Kaduna, the state capital.
A witness said that the crisis started when some Fulani youths stormed Ungwan Uka Village to avenge the death of a certain herdsman, allegedly killed by some village youths at a farm in the area.
The Commissioner of Police in Kaduna State, Mr Agyole Abeh, confirmed the incident.
Mr Abeh added that policemen and soldiers have been deployed to the troubled area, to ensure peace returns to the community.
