Lagos, Nigeria (CNN) -- The death toll from weekend violence in central Nigeria climbed to more than 200 Monday after members of a machete-wielding Muslim group attacked mostly Christian villages, officials said. More than 200 were dead and 32 injured, according to Choji Gyang, a religious affairs adviser to the head of Plateau state, who said bodies were still being recovered. Sani Shehu, president of the non-governmental agency Civil Rights Congress, put the number of dead at about 485 people. Twenty-six arrests had been made in connection with the violence, Gyang said. Nigerian Vice President Goodluck Jonathan put security on high alert Sunday and began operations to capture the "roving bands of killers" who attacked the town of Dogo Nahauwa, just south of Jos.
