Nigeria's top Muslim leader said on Wednesday that 300 people, mostly Muslims, were killed in Sunday's attacks by Christian militia in the town of Yelwa in the central Plateau state. Justice Abdulkadir Orire, secretary general of the Jama'atu Nasril Islam, described the killings in the remote farming town as "genocide" and said they took the death toll from three months of ethnic violence there to at least 700-800 people.
