France will make masks compulsory in all public indoor areas starting next week, Prime Minister Jean Castex announced on Thursday, as the authorities try to contain an uptick of coronavirus cases in recent days.

President Emmanuel Macron had initially suggested the rule would into effect Aug. 1, but Mr. Castex said the requirement would start earlier because Aug. 1 “sounded late.” An exact date was not announced.
Masks were already obligatory on public transportation in France, but there have been countless examples in recent days of people flouting social-distancing rules or not wearing masks inside — including during government meetings — raising concerns that the lack of precautions could trigger a wave of infections.
Britain announced similar measures this week, with face coverings compulsory in shops and supermarkets starting on July 24.
