PARIS (Dispatches) - French high-school students on Monday pressed on with a protest movement over learning conditions that has rocked the European nation since last week, with lessons disrupted at hundreds of schools. 
Clashes with riot police left hundreds of people injured, led to more than 5,000 arrests, mostly of minors, and jolted President Emmanuel Macron’s centrist administration.
There was a lull at the weekend, but protest organizers called for renewed demonstrations on Tuesday because the government had failed to produce “concrete measures”.
Since late September, pupils have barred the entrances to hundreds of schools, complaining of teacher absences, overloaded timetables, dilapidated classrooms and buildings ill-adapted to rising temperatures, among other grievances.
The teenage discontent has erupted with just months to go before elections next year to replace centrist President Emmanuel Macron.
More than 400 out of France’s 3,700 high schools, known as lycees, were partially or totally closed on Monday morning, the education ministry said.
A third of the 468 lycees for teenagers aged 15 to 17 were to be closed in the Paris region, authorities predicted on Sunday.
In the capital’s central third district on Monday morning, dozens of teenage students chanted in protest, as passing cars honked their horns in support, while others made their way into class.
“No means, no silence,” read one cardboard sign outside the Turgot high school. 
The government is also under pressure from trade unions that called a day of strikes last week to compel the new prime minister, Sébastien Lecornu, to rethink budget cuts and consider a form of wealth tax on the super-rich. The CGT trade union exhorted workers to sustain the pressure with demonstrations this week.
In the western city of Rennes, more than 20 pupils gathered outside the Montaigne lycee, one clutching a sign that read “Not enough teachers”, but staff allowed other students into their classrooms.
In Bordeaux, in the southwest, some students returned to the classroom while others continued to demonstrate, in the heavy presence of riot police.
Some protesters outside the Gustave Eiffel high school fired fireworks in the direction of the police, who responded with some tear gas, but overall the situation remained calm, AFP reporters said.
