SAN FRANCISCO, Nov. 28 (Xinhua) -- Amid the surge of COVID-19 cases, the U.S. state of California on Saturday moved San Francisco to the most restrictive Purple Tier in its pandemic classification, forcing most indoor activities to close by noon Sunday and placing the city under curfew starting Monday night.
San Francisco thus joined six Bay Area counties that were already in the Purple Tier. The retreat requires the city to halt indoor dining and shut down indoor operations such as museums, movie theaters, gyms and places of worship, according to a report by the San Francisco Chronicle.
