PARIS, FRANCE - JANUARY 10: Members of the public view leave pens and candles spelling 'Je Suis Charlie' in tribute at the Place de la Republique (Republic Square) on January 10, 2015 in Paris, France. Four hostages and three suspects were killed when police ended two separate sieges at a kosher supermarket and a printing company on an industrial estate, following Wednesday's deadly attack on Charlie Hebdo magazine. A fourth suspect, Hayat Boumeddiene, 26, escaped and is wanted in connection with the murder of a policewoman. (Photo by Jeff J Mitchell/Getty Images)
