Paris prosecutor Francois Molins has said the fate of the suspected organiser of Friday's attacks remains unknown after a police raid on a flat ended in bloodshed.
He said Abdelhamid Abaaoud was not among eight people arrested during the raid in the Paris suburb of Saint Denis yesterday.
However, he said human remains found in the rubble of the flat were 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.
Abaaoud is said to have organised the gun and bomb attacks in Paris. 129 people were killed in the horrific terror attacks.
Meanwhile, citing intelligence officials, Washington Post reported that Abdelhamid Abaaoud is dead.
