As reported by The Guardian:
Thousands of French university lecturers took to the streets today amid violent clashes as part of a growing “unlimited” strike movement against government higher education reform plans.
Lecturers and students marched in around twenty cities across the country, including Paris, Marseille and Bordeaux. In Strasbourg, police used tear gas against demonstrators (1600 according to police, 2500 according to unions), some of who threw projectiles at officers. Police occupied the steps of the university’s main building.
In total, an estimated 45% of classes are affected across the country, with unions claiming that more than one in two lecturers are not working.
