Days after France witnessed three days of deadliest militant attacks, beginning with massacre of journalists and cartoonists in satirical magazine Charlie Hebdo office killing 17 people so far in sieges, several world leaders, including President Francois Hollande, in a show of solidarity against terrorism marched with more than a million others in Paris on Sunday to send a strong message to the radicals.
In a show of unity, about 40 world leaders joined the start of the march which is considered to be one of largest demonstrations the country has seen in recent times.
France witnessed a dark day in its history on Jan 7 with gunmen attacking the Paris office of French satirical magazine Charlie Hebdo and killing at least 12 people , including cartoonists and two policemen, as global leaders joined to condemn the incident.
The militants suspected of orchestrating France’s worst terror onslaught - two brothers of Algerian descent and an associate of African origins - were killed.
Also dead were four of the people held hostage at Hyper Cacher, the kosher supermarket located in eastern Paris.
Altogether, 20 people, including the three militants, died in three days of bloodshed.
