Impromptu shrines are springing up across Paris.
Candles and flowers have been left at the places where scores of people were killed and injured last Friday night.
But people are also gathering to pay their respects at the Place de la Republique in the city centre.
French Interior Minister Manuel Valls says the identity of 103 people has been established so far.
“20 to 30 people have not yet been identified. They will be in the coming hours but the wait is unbearable. I have spoken to the families and they have all told me of their immense pain. The nation must gather round these people, today and in the coming days.”
