PARIS, FRANCE - JANUARY 10: 'Je suis charlie' (I am Charlie) and 'Je suis policier' (I am a policeman) signs are tied to a railing near the site where four hostages were killed during a terrorist attack at kosher supermarket 'Hyper Cacher' yesterday in the Porte de Vincennes area 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' french satirical magazine. A fourth suspect, Hayat Boumeddiene, 26, escaped and is wanted in connection with the murder of a policewoman. (Photo by Marc Piasecki/Getty Images)
