Tens of thousands of demonstrators took to the streets across France on Saturday in a nationwide day of action against the cost of living, with police firing tear gas at Place de la République in Paris and reports of a tourism office set ablaze in Lyon as the unrest spread beyond the capital.

France's Interior Ministry counted roughly 140 separate protest actions involving nearly 33,000 people nationwide, according to Euronews, though organizers had publicized a far larger number of planned gatherings. Arrest tallies climbed through the day as police moved to break up the largest crowds; national figures settled around 166 people detained, with the Paris police prefecture separately reporting more than 100 arrests in the capital alone.

In Marseille, some demonstrators forced their way into the town hall atrium. Police used tear gas at Place de la République in Paris after clashes broke out between officers and protesters there.

The demonstrations draw together student groups, trade unions and self-described "yellow vest" activists in a loose coalition united mainly by anger over stagnant wages, public spending cuts and rising prices — with fuel costs linked to the ongoing Iran war adding fresh grievance on top of a protest movement that began in late September over school staffing shortages and overcrowded classrooms.

THE UNREST HAS BECOME AN EARLY FLASHPOINT AHEAD OF NEXT YEAR'S PRESIDENTIAL ELECTION

Interior Minister Laurent Nuñez said the police response had been proportionate "in almost all cases" and that 715 officers had been injured over the course of the broader protest wave in recent weeks. Prime Minister Sébastien Lecornu separately rejected allegations of racism in police tactics against demonstrators as a "lie," a charge that has dogged the government's handling of the student-led protests since they began.

The unrest has drawn attention beyond France's borders. Iran's government has accused Paris of using excessive force against protesters and of applying a double standard, contrasting France's past calls for restraint toward demonstrators inside Iran with its domestic crackdown, according to Kurdistan24, which reported Iran's foreign ministry summoned France's ambassador in Tehran over the issue.

Saturday's turnout is widely seen as a test of whether the cost-of-living movement can sustain momentum into the winter. With fuel prices nudging higher because of the Iran war and no sign the government plans to reverse the spending measures that triggered the original school protests, organizers have vowed further nationwide actions are already being planned, raising the prospect of recurring clashes as France heads toward its next presidential race.
