The Paris prosecutor has said the fate of the suspected organiser of Friday's attacks remains unknown after a police raid on a flat ended in bloodshed.
Francois Molins told reporters Abdelhamid Abaaoud was not among eight people arrested during the raid in the Paris suburb of Saint Denis.
However, human remains found in the rubble of the flat had still to be identified.
A woman blew herself up and another suspect was shot dead during the raid.
An interior ministry spokesman said the building was so badly damaged that it is unclear if there is a third body in the rubble.
