French experts are working to establish whether the suspected ringleader of the Paris attacks was among those killed in a police raid on a flat on Wednesday.
Police said Abdelhamid Abaaoud was the target when officers stormed the flat in the Paris suburb of Saint Denis.
The Paris prosecutor said neither he nor suspect Salah Abdeslam were among eight people arrested, but at least two bodies had still to be identified.
Meanwhile, French MPs are due to vote on extending a state of emergency.
Militant group Islamic State (IS), which controls parts of Syria and Iraq, has said it was behind the attacks last Friday, when gunmen and suicide bombers killed 129 people and injured hundreds.
