Charlie Hebdo

Muslims were among the first people at the scene of last week's attacks in Paris. An employee of the kosher supermarket saved hostages, and a policeman died responding to the Charlie Hebdo shootings.

Jewish and Muslim communities have lived together for decades in Sarcelles, about 10 miles from Paris. But locals say last week's attacks in Paris have heightened awareness of religious differences.

While France's leaders had feared an attack, Ambassador Gerard Araud says, "what happened was in a sense maybe worse than what we were expecting, because it was done in a very professional way."
