More than 700,000 people have defiantly rallied throughout France in solidarity with victims of this week's Islamist attacks, on the eve of a march in Paris expected to dwarf that figure.
The massive rallies on Saturday are in tribute to the 17 victims of the three-day killing spree, and security forces were mapping out a major deployment aimed at preventing fresh violence.
World leaders including British Prime Minister David Cameron, German Chancellor Angela Merkel and Israeli Prime Minister Benjamin Netanyahu were set to attend Sunday's march in support of France, badly shaken by the violence.
The king and queen of Jordan and Russian Foreign Minister Sergei Lavrov are also among those set to take part.
French Prime Minister Manuel Valls predicted that millions of people would turn out on Sunday to honour the dead and decry the fundamentalist attacks.
"I have no doubt that millions of citizens will come to express their love of liberty, their love of fraternity," he told thousands gathered near where a gunman killed four hostages at a kosher supermarket on Friday.
"France without Jews is no longer France," Valls added.
In Jerusalem, Netanyahu told French Jews Saturday that Israel was their home.
"To all the Jews of France, all the Jews of Europe, I would like to say that Israel is not just the place in whose direction you pray, the state of Israel is your home," he said in a televised statement, referring to the Jewish practice of facing Jerusalem during prayer.
"Unless the world comes to its senses, terror will continue to strike in other places," he added in remarks on his official Twitter account.
Security levels were kept at France's highest level, with the girlfriend of one of three gunmen killed in a fiery climax to twin hostage dramas on Friday still on the loose.
But a police source revealed that 26-year-old Hayat Boumeddiene, the "armed and dangerous" partner of Amedy Coulibaly who took shoppers hostage in the Jewish supermarket, was not in France at the time of the killings.
Coulibaly shot dead a young policewoman on Thursday and then took the shoppers hostage Friday, and while police had suspected Boumeddiene may have had a role in her partner's violent acts, she was likely in Turkey then, the anonymous source said.
The source, who declined to be named, said investigators were checking whether she was now in Syria.
At the same time, a judicial source said five other people held after the assaults, including the wife of Cherif Kouachi - one of the two brothers who attacked the Paris office of the satirical weekly Charlie Hebdo on Wednesday, were all released on Saturday.
Meanwhile, France deployed hundreds of troops around Paris on Saturday, further beefing up security on the eve of Sunday's march.
Already, Saturday's rallies drew some 700,000 onto the streets in cities across France in poignantly silent marches after the nation's bloodiest week in more than half a century.
