JOS, Nigeria (AP) -- Nearly 3,000 people have fled to a neighboring state after hundreds were slaughtered in several mostly Christian villages over the weekend, aid officials said Thursday.

On Thursday, thousands of women took to the streets in protest, singing and waving branches full of green leaves -- a traditional sign of protest. They also carried Bibles and crosses made out of scrap lumber. One held a sign that said: ''God hears when we cry. Just be warned.''

At least 200 people, most of them Christians, were slaughtered on Sunday, according to residents, aid groups and journalists. The victims included dozens of children. In January, more than 300 people were killed, most of them Muslims.
