People in France will risk a fine of 135 euros ($154) starting Monday for failure to comply with a new decree to wear a mask in public places indoors, the government announced.

As officials noted signs of an uptick in virus circulation, Prime Minister Jean Castex on Thursday said masks will become compulsory in enclosed public spaces from next week in a bid to prevent a second wave of coronavirus infections.

Masks are already required on public transport, punishable with a fine of the same amount, in a country that has lost over 30,150 people to the epidemic.
