Live: France's Yellow Vests throw their weight behind mounting student protests

On the eve of nationwide cost-of-living protests in France, President Emmanuel Macron pleaded for calm, warning that the demonstrations could potentially escalate into violent clashes. Authorities are concerned about the potential for a six-month run-in to the country's presidential election, with Paris authorities banning protests in the city's center.

The Yellow Vest movement, which previously held street protests against Macron's government, initiated the "yellow and youth" demonstrations on Saturday, calling upon teachers, students, workers, pensioners, and farmers to participate.

Interior Minister Laurent Nunez suggested authorities anticipate a significant turnout, with 40,000 people in Paris and nearly 200,000 nationwide. A police source gave a similar estimate. Macron emphasized the importance of exercising the right to protest while also respecting people and property. He also noted that the legitimate demands of the students are being exploited for political purposes.

The unrest has attracted the attention of both France's far-left and far-right parties, with Jean-Luc Melenchon, the leader of the far-left France Unbowed party, supporting the student protests and participating in a demonstration. Marine Le Pen, who leads in presidential election polls, has aligned her National Rally party with the police. The merging of student protests with public anger over the cost-of-living crisis could significantly impact Macron's government ahead of the April and May election.

Prime Minister Sebastien Lecornu has established a crisis cell to monitor the demonstrations, expressing fears of clashes following urban violence during the student protests. Lecornu is seeking approval for a cost-cutting budget from parliament, while protesters demand better protection from inflation and increased spending on public services, especially education.

Anger towards perceived police brutality during the student protests has also grown, as several teenage protesters were seriously injured, and thousands were arrested.

Organizers of the Saturday demonstrations have launched a website listing over 600 planned protests across France. Both authorities and demonstrators are preparing for possible violence, with Paris police chief Patrice Faure banning demonstrations near the Elysee presidential palace, the prime minister's office, and the Champs-Elysees shopping avenue. Police also prohibited a major march through the city's heart, and negotiations for an alternative route failed to produce an agreement.

The Paris demonstration was set to begin at 2:00 pm (1200 GMT) at Republique square and proceed to northern Paris. Nunez informed France 2 that police could employ stun grenades in extreme cases of urban violence. He had previously suspended their use during the student protests following an incident where a stun grenade injured a 15-year-old.

Authorities warned that actions blocking major roads or essential facilities would not be tolerated. Demonstrators have created a smartphone app to track the real-time locations of police, tear gas, and helicopters.
