France is considering expanding rules over when people should wear face masks, according to the country's new prime minister, reports The Independent.
Jean Castex, who took on the role in early July, said the main focus was on indoor spaces.
"The issue of widening the use and wearing of masks is under a lot of consideration," he told reporters in French Guiana over the weekend.
"In particular, that would concern as a matter of priority all places - whatever they are - which are enclosed."
France's health secretary, Olivier Véran, later said the issue was "on the table".
People must wear face masks on public transport in France.
