Charlie Hebdo attacks: Paris witnesses massive march for unity

French President Francois Hollande was with top world leaders like  Israeli Prime Minister Benjamin Netanyahu and UK PM David Cameron as they marched along with large number of people on Paris to demonstrate their solidarity after the attacks on satirical magazine Charlie Hebdo, police officers and a supermarket hit the country.

Hollande said "Paris is today the capital of the world."

He said the entire country will rise up and show its best side.

Cameron tweeted: "I've just arrived at the Élysée to meet President Hollande. We'll March together for our values and those murdered at #CharlieHebdo."

Security has been beefed up across the country following the attacks and specially with the country witnessing such a march with top leaders participating in it.

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.

During the assault by police officers on the kosher supermarket, Special Forces were sprayed with bullets. Sources said the supermarket had been booby-trapped, making it especially hard to get to the hostage taker.

Altogether, 20 people, including the three militants, died in three days of bloodshed.

President Francois Hollande, in a solemn address to the nation on Friday, described as the work of “madmen, fanatics” who had created “a tragedy for the nation that we were obliged to confront.”

Meanwhile, a video has emerged which showed the supermarket attacker, Amedy Coulibaly, pledging allegiance to the so-called militant group Islamic State.
