Night of the Barricades in Paris

Following a ban on demonstrations and the closure of universities and sections of central Paris, thousands of students hit the streets to protest. Riot police refuse to allow demonstrators to cross the Left Bank, the crowd creates makeshift barricades, and a battle ensues.
