Mass Unity Rallies Held Around The World Following Recent Terrorist Attacks

LONDON, ENGLAND - JANUARY 11: The National Gallery is lit in the blue, white and red colours of the national flag of France in tribute to the victims of the terrorist attacks in Paris on January 11, 2015 in London, England. 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 Rob Stothard/Getty Images)
