World leaders join tribute

Hundreds of thousands march in Paris to stand up against terrorist attacks

Dozens of world leaders including Muslim and Jewish statesmen joined hundreds of thousands of French citizens marching in Paris amid high security in an unpredecented tribute to victims of this week's Islamist militant attacks.

President Francois Hollande and leaders from Germany, Italy, Israel, Turkey, Britain and the Palestinian territories among others, moved off from the central Place de la Republique ahead of a sea of French and other flags. Giant letters attached to a statue in the square spelled out the word "Pourquoi?" (Why?) and small groups sang "La Marseillaise", the French national anthem.
