About 10 vehicles were involved when a bridge collapsed during a sudden and violent storm in the northern Italian port city of Genoa, authorities said.
A 200-metre (650ft) section of the Morandi Bridge collapsed over an industrial zone, according to reports.
Firefighters have said there are also concerns about gas pipes.
Video captured the sound of a man screaming: “Oh god, oh, god.”
Other images showed a green truck that had stopped on the bridge just yards short of the gaping hole in the road surface.
