New measures have been announced by the French government as countries across Europe battle the spread of the Omicron variant of the coronavirus.
There were no major moves such as a new lockdown or curfew but nightclubs will be shut from December 10 for a month.
Prime Minister Jean Castex said the cabinet had managed to rule out tougher restrictions such as regional shutdowns or a national curfew because of the success of the vaccination campaign so far.
But Castex said the school alert level was being raised to 3 (level 4 is the highest).
This means all children must wear face masks at all times inside and outside and there is a new clampdown on trying to avoid pupils mixing between classes and at mealtimes.
