French president Francois Hollande has opened a national day of commemoration in France, one year after the Paris attacks that killed 130 people.
Hollande unveiled a plaque covered by a small French flag at the national stadium in memory of the single person killed there, Manuel Dias, and the numerous wounded.
The president remained silent at the ceremony outside the Stade de France and was not expected to speak as he unveils plaques at the seven sites hit by Islamic extremists.
Instead, the victim's son Michael spoke, saying his Portuguese-born father was "proof that integration is possible, necessary" to fight the stigmatisation that leads some youths into violence.
It was a reference to the attackers who were European citizens of foreign descent. He said: "Long live tolerance, long live intelligence, long live France."
Hollande will go on to visit cafes and bars targeted by extremists on November 13 2015, including Bonne Biere and Belle Equipe, finishing by unveiling a plaque at music venue the Bataclan.
Eighty-nine people were killed in a massacre at the venue where Eagles Of Death Metal were performing, including Briton Nick Alexander. Former Police frontman Sting reopened the Bataclan on Saturday night.
Notre Dame Cathedral will hold an evening service commemorating the attacks, which the Islamic State group claimed responsibility for.
In addition to those killed, nine people remain in hospital. The government says more than 600 people are still receiving psychological treatment after the attacks.
France declared a state of emergency after the November 13 attacks, which is still in force.
Prime minister Manuel Valls warned this weekend: "Yes, terrorism will strike us again." But he said: "We have all the resources to resist and all the strength to win."
