France reimposes curfew in Paris, arrests ultra-left arsonist as protests escalate

France reimposed a curfew in central Paris and imposed restrictions in Marseille and Lyon after a relatively quiet day, with weekend protests planned and a 'massive deployment' of police and military, including the Sentinel Force, promised. An 'environmental activist' was arrested for arson at Limoges City Hall, with French intelligence linking ultra-left elements to the unrest. This marks an escalation in domestic security measures, indicating sustained protest activity and potential for further violence.
