Some 500 extra troops are being deployed around Paris after three days of terror in the French capital killed 17 people.

Interior Minister Bernard Cazeneuve said all necessary measures were being taken to protect the country.

Police in France are hunting for any accomplices of three gunmen killed by police on Friday after two sieges.

About 700,000 people have taken part in marches across France to remember the victims, Mr Cazeneuve said.

Mr Cazeneuve said France would remain on its highest state of alert "for the next few weeks".

He promised "exceptional measures" for a massive unity march in Paris on Sunday, including more than 5,500 police and military personnel.

Those set to attend the rally include UK Prime Minister David Cameron, German Chancellor Angela Merkel, Turkish Prime Minister Ahmet Davutoglu, Spanish Prime Minister Mariano Rajoy and Russian Foreign Minister Sergei Lavrov.

"Sunday, the French people will cry out their love of liberty," said Prime Minister Manuel Valls.

France would be "firm and relentless in the face of the enemies of liberty", he added, urging all people to "assume their responsibilities".
Family 'devastated'

Silent marches have been held in cities including Paris, Orleans, Nice, Pau, Toulouse and Nantes to remember the victims of this week's violence.

Some protesters held banners that read "I am against racism", "unite", or "I am Charlie", in reference to Charlie Hebo, the satirical magazine whose offices were attacked on Wednesday.

The family of Ahmed Merabet, one of the police officers killed during Wednesday's attack, gave an emotional news conference on Saturday.

Mr Merabet was "Muslim, and very proud of being a police officer and defending the values of the Republic", his brother Malek Merabet said.

He added that the family was "devastated by this act of barbarity, and shared the pain of the families of all the victims".

"I want to say to all the racist, Islamophobic, anti-Semitic people, that one must not amalgamate extremists and Muslims," Mr Merabet's brother added.

The family said they were "proud" of the gatherings that had taken place to commemorate the victims, saying they proved that France could be united.

Hostages' bodies

The violence began when two brothers, Cherif and Said Kouachi, killed 12 people and injured 11 in an attack on the offices of Charlie Hebdo magazine on Wednesday.

On Friday, the brothers were killed by police in Dammartin-en-Goele, 35km (22 miles) north of Paris, as they emerged from a besieged warehouse building firing their automatic weapons.

One hostage had earlier been released and a second employee, who was hiding in the building's cafeteria, was freed by police.

Police shortly afterwards launched an assault on a supermarket in eastern Paris where gunman Amedy Coulibaly had been holding several hostages.

Police killed Coulibaly and rescued 15 hostages. They found the bodies of four hostages who are believed to have been killed before the assault.

The four victims have been identified as Yoav Hattab, Philippe Braham, Yohan Cohen, and Francois-Michel Saada. Their names were released by the Representative Council of French Jewish Institutions.

Some of the hostages were able to stay safe because employee Lassana Bathily helped them hide in the market's cold store, French media report.

Police are searching for Hayat Boumeddiene, Coulibaly's partner.

Police sources have told French media that she may have been out of the country at the time of the attacks. They believe she has travelled to Turkey.

Security officials have said they were aware of Coulibaly and the two brothers. Said Kouachi was known to have travelled to Yemen in 2011.

Both brothers are understood to have been on UK and US watch-lists.

According to French prosecutors, Coulibaly knew one of the brothers and their respective partners had spoken on the phone more than 500 times.
