VATICAN TO MANDATE VACCINES FOR EMPLOYEES 

Both employees and employers risk fines if they don’t comply. Workers in the public sector can be suspended if they show up five times without a Green Pass. This summer, Green Passes were required in Italy to enter museums, theaters, gyms and indoor restaurants, and take long-distance trains and buses or domestic flights.

The protesters held an authorized protest in Piazza Del Popolo. Then some left the vast square and clashed with police as they went to an unauthorized march. Police in helmets and carrying shields and batons blocked them from marching down a street that runs past Premier Mario Draghi’s office.
