At least three people, including a child, died in France overnight after a blaze engulfed an abandoned factory that was housing nearly 300 Roma squatters in the southeastern city of Lyon, officials said on Monday. Up to seven people in all could have perished in the fire, which began shortly after midnight and completely destroyed the building, fire fighters and police said. Officials said two women and a child were confirmed dead. Local human rights activists said the building was mostly used by women and children.
