• Europe live: latest updates from protests in France

Before dawn on Tuesday outside the Lycee Sophie-Germain in central Paris, hundreds of teenagers dragged wheelie bins, metal barriers and shopping trolleys to build a barricade outside the front door of their secondary school.

Climbing to the top of the piles of bins, pupils held banners calling for more funding and greater equality in French schools. But they were also protesting against French riot police, who have been accused by human rights groups of using disproportionate force against children in what is fast becoming the biggest youth protest movement in decades.
