President Emmanuel Macron said, after chairing a meeting of key ministers and intelligence officials, that curfews and other security measures would be imposed, including bans on "groups without legitimacy" holding protests.

"The priority is a return to calm," he said, adding that he would chair a defence council meeting of key ministers on Friday to decide "the next steps" for new nationwide demonstrations called for Saturday and afterwards.
