In France and around the world, thousands of people joined rallies and vigils in memory of the victims of the attack on the offices of Charlie Hebdo in Paris.

Many who poured into Place de la Republique in Paris near the site of the attack waved pencils and pens. As a show of support for free speech, many held placards with the slogan "Je Suis Charlie".
