The eerie sight of empty streets in Italy's usually packed city centres returned this weekend after strict new rules came into force. The streets in Milan, Turin, and other cities within the country's four 'red zone' regions have been almost empty as movement was strictly curtailed from Friday.

Under the new three-tier system of restrictions, Calabria, Lombardy, Piedmont and Val d'Aosta have been under the strictest measures since Friday.In red zones, restrictions on movement resemble those imposed earlier this year during the severe national lockdown, with residents warned not to leave their homes other than for essential reasons.
