Up to six members of a terrorist cell may still be at large after the Paris attacks, according to French police.

One of them has been spotted driving a car registered to the partner of one of the dead attackers, according to the authorities.

Police officials said a search was being carried out of the Paris area for the Mini Cooper car registered to Hayat Boumeddiene.

She is the girlfriend of Amedy Coulibaly, who gunned down a police officer before killing four people in a Jewish supermarket last Friday.

The attack came after co-conspirators Said and Cherif Kouachi massacred 12 people at the offices of satirical magazine Charlie Hebdo on Wednesday.

All three killers were finally cornered and died in police assaults on Friday.

The authorities say Coulibaly "undoubtedly" had an accomplice.

Boumeddiene remains on the run amid reports she has fled to Syria. Footage emerged of her arriving at Istanbul Airport before the attacks in Paris took place.

In a video, Coulibaly defended the atrocities and pledged allegiance to the terror group Islamic State.

Meanwhile, France has deployed nearly 5,000 police to protect Jewish schools and mobilised thousands more security forces following the terror attacks.

Three million copies are to be published of this week's Charlie Hebdo special "survivors' issue", with many of them to be made available outside of France and offered "in 16 languages".

In a show of defiance to the extremists, the edition produced after last week's newsroom massacre will feature a cartoon depiction of the Prophet Mohammed holding up a sign saying "Je Suis Charlie".
