Caption:PARIS, FRANCE - JANUARY 11: Demonstrators make their way along Boulevrd Voltaire in a unity rally in Paris following the recent terrorist attacks on January 11, 2015 in Paris, France. An estimated one million people are expected to converge in central Paris for the Unity March joining in solidarity with the 17 victims of this week's terrorist attacks in the country. French President Francois Hollande will lead the march and will be joined by world leaders in a sign of unity. The terrorist atrocities started on Wednesday with the attack on the French satirical magazine Charlie Hebdo, killing 12, and ended on Friday with sieges at a printing company in Dammartin en Goele and a Kosher supermarket in Paris with four hostages and three suspects being killed. A fourth suspect, Hayat Boumeddiene, 26, escaped and is wanted in connection with the murder of a policewoman. (Photo by Christopher Furlong/Getty Images)
