Caravan brings attention to rising violence in southern Mexico

A caravan to highlight rising violence in southern Mexico wraps up this evening. The same movement that traveled through northern Mexico in a caravan earlier this summer, turned their attention to the violence in the south. More than 600 victims of violence, activists, human rights observers and journalists spent ten days traveling through seven states to document how the drug war has affected Mexico's poorest regions.
