Several Kalashnikovs have been found in an abandoned car believed to have been used by some of the Paris attackers, French judicial sources say.
The black Seat car was found in the eastern Paris suburb of Montreuil on Sunday, suggesting some of the attackers got away.
Earlier, the first of the seven dead attackers was named as Ismail Mostefai. Six people close to him are in custody.
France is in three days of mourning for the 129 people killed in the attacks.
Prime Minister Manuel Valls said most of the bodies had been identified and that the process should be completed in the coming hours.
A special service for the victims, including 350 people wounded and other survivors, will be held at Paris's Notre Dame Cathedral later on Sunday.
