million students and labourers participated. Organizers estimated the number was closer to 1.5 million. Students (including high school students) demonstrations began to become daily, and often were the site of clashes with the police. 21 March After large demonstrations and subsequent riots on 16 and 18 March, on the 21st the Dijon students' union called for a general strike, as demanded by left-wing papers such as Libération. A meeting that day of various labour and student groups agreed for another 'day of action' against the law, including strikes, demonstrations and university occupations across the country. 23 March Riots erupted again after a day of relative calm in several cities in France.
