MILAN (AP) — A bridge over an industrial area in the Italian city of Genoa partially collapsed during a sudden and violent storm on Tuesday, leaving vehicles crushed in the rubble below.

Italian media reported that there were deaths, but Maria Luisa Catalano, a police official in Genoa, said that authorities were still involved in rescue efforts and did not yet know the number of victims or injured.

The disaster occurred on a highway that connects Italy to France and other vacation resorts on the eve of a major Italian holiday on Wednesday, Ferragosto, and traffic would have been heavier than usual as many Italians traveled to beaches or mountains.
