France has marked one year on from the Paris attacks with a series of sombre events, including a silent tour of the sites where 130 people were killed by Islamic extremists.

Under heavy security, President Francois Hollande and Paris Mayor Anne Hidalgo began the day by visiting the sites where crowds had been eating, drinking, or revelling at the time of the attacks.

Three teams of extremists coming from neighbouring Belgium last year targeted bars and eateries, a concert hall, and the national stadium, turning scenes of Friday night fun into bloodbaths.

It was the worst extremist violence ever to hit France.

In silence, Mr Hollande pulled French flags from plaques commemorating the victims, whose names were also read out.

At the national stadium, the son of the only person killed at the site addressed the crowd.

Michael Dias said his Portuguese-born father Manuel was "proof that integration is possible [and] necessary" to fight the stigmatisation that leads some youth into violence.

He said: "Long live tolerance, long live intelligence, long live France".

Mr Hollande and Ms Hidalgo were accompanied by Prime Minister Manuel Valls and Interior Minister Bernard Cazeneuve at a memorial ceremony near Bonne Biere, one of six cafes targeted during the attacks.

There were no deaths at the Comptoir Voltaire brasserie except for suicide bomber Brahim Abdeslam, a 31-year-old Frenchman and the older brother of Salah Abdeslam, the only survivor among the three attack teams who is now jailed in France.

The Bataclan concert hall, the scene of the deadliest attack, was the final stop in Sunday's ceremony, and the 90 names of those killed were read out before a minute of silence was observed.

Following the unveiling of two plaques, people were able to pay their respects to those killed.

It followed the reopening of the Bataclan on Saturday night with a sold-out concert by British pop legend Sting.

Hannah Schumann, a nurse, said: "Everybody is emotional. I'm crying."

In a sign of hope, several hundred balloons were released from the nearby town hall in the presence of Mr Hollande, and lanterns were set to be floated along the Canal Saint-Martin.

Attendees still trying to heal

Families of victims, security and rescue forces and some still trying to heal were among those present at the ceremonies.

In addition to those killed, nine people remain hospitalised from the attacks and others are paralysed.

The Government says more than 600 people are still receiving psychological treatment after the attacks.

"This anniversary is a further reminder of the volatile terrorist threat faced in Europe today," said a statement by Europol, the European police agency.
