At least six people have died in violent rainstorms sweeping across Italy today with the Tuscan city of Livorno taking the brunt of the flooding. Four people from the same family were found dead in a flooded house in the city, where 40cm of rainfall in four hours transformed streets into rivers and washed away cars. <br/><br/>The Corriere della Sera daily said the dead were a little girl, her parents and a grandparent. Mayor Filippo Nogarin said casualties could increase because several people are missing. Train service was interrupted in parts of the Tuscan coastal area. Underpasses were being closed as a precaution in the capital Rome.
