Rock star Bono today left flowers and an emotional message at the scene where Mohamed Lahouaiej Bouhlel killed 84 people after driving a 19-tonne lorry down the famous Nice promenade.
The U2 lead singer, 56, was caught up in the terror attack and had to be rescued from a nearby restaurant by anti-terrorist police.
And he today wrote a poignant message saying that 'there is no end to grief' - lyrics used on the band's track California (There Is No End To Love).
The signer-songwriter was on the terrace of 'La Petite Maison', close to where the Bouhlel, 31, drove his hired lorry into crowds enjoying a firework display while celebrating Bastille Day.
After the atrocity, Bono tweeted a message of support to the victims of the massacre and he was today photographed laying flowers to pay his respects.
A minute's silence was today held on the Promenade des Anglais, the famous seafront where helpless revellers - including 10 children - were hit by the terrorist's lorry.
The famous singer-songwriter laid flowers and wrote a poignant message on a piece of card.
He wrote: 'There is no end to grief that's how I know there is no end to love. Bono. With respect for lives lost here on 14/7/16.'
Bono's emotional message is similar to some of his own lyrics and his visit to the promenade comes after the band tweeted their support for the victims and the people of Nice.
The message which was posted to U2's Twitter account read: 'Love is bigger than anything in its way - Bono, Edge, Adam, Larry.'
After Bouhlel drove a hired lorry into crowds enjoying a holiday firework display Bono and other diners were gripped by fear.
Anne-Laure Rubi, the owner of the upmarket restaurant - which is popular with a number of celebrities - said: 'Suddenly I saw people running, without shouting. It was a silent panic - it was extraordinary.'
Ms Rubi told La Parisienne magazine that 'by reflex' she grabbed the arm of Christian Estrosi, the former Nice Mayor, who was sitting close to Bono.
She said: 'He was on the phone. He didn't want to say much. I think he was just learning about the attack'.
Ms Rubi's staff pulled down the shutters, and instructed everybody to hide and remain calm, until the all clear was given.
Bono owns a home in the nearby town of Eze, and had been relaxing with friends when the atrocity started at around 10.30pm last Thursday.
As the slaughter on the Promenade des Anglais became clear, the star was eventually rescued by armed officers who led him to the nearby Massena square.
Another diner said: 'It took around half an hour for the police to get us out. Like everybody else, Bono had to put his hands on his head, and was told to remain calm.
'The police were clearly very worried that terrorists might still be at large, and everybody was under suspicion.'
There were fears at the time that the nearby Meridien Hotel might be under siege, and that bombs were set to explode.
Also in the restaurant was Eric Dupont-Moretti, the lawyer of Real Madrid footballer Karim Benzema, and the restaurateur Alain Ducasse.
It was the second time that Bono has found himself close to a major terrorist attack in France.
Last November he and his band were rehearsing for a concert in Paris, when Islamic State operatives attacked the nearby Bataclan theatre, killing 89 people.
Rather than leave the French capital, the four U2 members made their way to the Bataclan the next morning, and paid homage to the deceased.
IRA and Irish unionist terrorism is a constant theme in the music of Bono, who as a boy was a first hand witness to the Dublin and Monaghan bombings which killed 33 in 1974.
