France has banned all indoor gatherings of more than 5,000 people, as part of efforts to contain the country's coronavirus outbreak.
Measures announced after an emergency cabinet meeting also include the cancellation of the Paris half-marathon which was to be held on Sunday.
In the worst-hit area, north of Paris, all public gatherings have been banned.
The total number of cases of the new coronavirus in France rose to 100 on Saturday. Two patients have died.
Globally, more than 85,500 cases have been confirmed in more that 50 countries. The death toll is over 2,900.
The vast majority of infections and deaths are in China, where the virus originated late last year.
The US has reported its first death from the virus, in the north-west state of Washington. Details of the person's identity have not yet been released, but officials said they would give a press conference at about 21:00 GMT.
The US has reported at least 59 coronavirus cases, including four of unknown origin.
What is the latest in France?
"Our goal at this stage is limit the spread," Health Minister Olivier Véran said after Saturday's cabinet meeting.
Among the events affected by the prohibition of large indoor gatherings is Paris's annual agricultural fair. Its final day, which was scheduled for Sunday, has been cancelled.
The Paris half-marathon was scrapped as part of a new ban on events that involve "mingling with people from areas where the virus is prevalent".
Football matches are unaffected.
The French area with most cases is Oise, north of Paris. Most of the 18 infections there appear to be linked to a 60-year-old schoolteacher who died of the Covid-19 respiratory disease earlier this week.
Public gatherings have been banned in Oise, as well as a town in the French Alps where cases have been reported.
The government has urged residents of the worst-hit areas to avoid "non-essential travel" and "work from home if possible ".
