A road collapse has plunged a row of parked cars into an underground water pipeline.
Firefighters have been working to prevent other possible road collapses.
The 200-metre long hole opened up early on Wednesday morning along the Arno river bank close to the famous Ponte Vecchio.
Some local residents have been evacuated as a precaution.
A firefighter report says the hole was caused by the collapse of the water pipe.
There have been no casualties.
