A flash flood in Palermo, Sicily, left dozens of people trapped in their cars on Wednesday.
Mud and water swept away the vehicles and left them blocked in a highway underpass.
Drivers and passengers escaped and swam to safety, but a witness reported seeing two people disappear in the water.
Firefighters worked all night searching for them.
Two children, who were stuck in a car with their parents, have been hospitalised with hypothermia.
