French President Francois Hollande led world leaders and French citizens on Sunday for a massive rally in Paris for unity and freedom of expression, to honour 17 victims of three days of extremist attacks in which three gunmen attacked a magazine office, kosher supermarket and police.
Tens of thousands of people turned out for the demonstration.
During the march, Hollande greeted members of the police and employees of the French satirical magazine Charlie Hebdo that was attacked on Wednesday.
The three days of horror began on Wednesday when brothers Said and Cherif Kouachi stormed the newsroom of Charlie Hebdo, killing 12 people.
Al-Qaida's branch in Yemen said it directed the attack by the masked gunmen to avenge the honour of the Prophet Muhammad, a frequent target of the weekly's satire.
On Thursday, police said Coulibaly killed a policewoman on the outskirts of Paris and on Friday, the attackers converged.
While the Kouachi brothers holed up in a printing plant near Charles de Gaulle airport, Coulibaly seized hostages inside a kosher market.
It all ended at dusk Friday with near-simultaneous raids at the printing plant and the market that left all three gunmen dead. Four hostages at the market were also killed.
