Gunmen in central Nigeria's Plateau state killed 37 people in a pre-dawn raid Tuesday, the military said, the latest unrest to hit the area gripped by a decade-long sectarian conflict. "At about 2:00 am (0100 GMT) unknown gunmen carried out an attack" in four villages, said area military spokesman Salisu Mustapha. "The attackers killed... 13 persons in Katu Kapang, eight in Daron, nine in Tul and seven others in Rawuru."
