Immigrant riot
There have been scuffles between the workers, and police and residents in the streets of the Calabrian town of Rosarno since Thursday.
The violence in the crime-ridden and volatile area started after two immigrants were wounded by unidentified gunmen.
Protesters then stoned police, attacked residents, damaged shop windows and cars.
The Interior Ministry said 14 people – including officers, protesters and residents – were injured, while seven immigrants were arrested.
