California is re-imposing restrictions amid a spike in COVID-19 cases.

Governor Gavin Newsom ordered to close bars and restaurants, cinemas, zoos, and museums throughout the state. Churches, gyms and hairdressers will close in the 30 pandemic-affected districts.

"I hope all of us recognise that if we were still connected to some notion that somehow when it gets warm it's going to go away or somehow it's going to take summer months or weekends off - this virus has done neither," BBC reported quoting Newsom.

"We are now effective today requiring all counties to close their indoor activities, their indoor operations in the following sectors: restaurants, wineries, tasting rooms, movie theatres, family entertainment centres, zoos and museums, card rooms and the shuttering of all bars. 

"This is in every county in the state of California," the governor said.

California has confirmed over 330,000 COVID-19 cases, with over 7,000 deaths.
