Though the ISIS was slow to claim responsibility for the attack, it has said that the person who drove the truck and killed over 80 people was their soldier.
On Friday, following the attack the ISIS was in celebratory mode. There were posts on pro-ISIS handles which directed France to turn the lights off at the Eiffel Tower until they take over the nation.
Analysts that OneIndia spoke to say that the Nice attack was more of an attempt to tell France to slow down in Syria and Iraq. French President Francois Hollande had said on Friday that they would strengthen France's role in both Iraq and Syria.
It may be also recalled that the ISIS had put out a 'Do-it-Yourself' manual for ISIS sympathisers in which it had spoken about attacking with cars. In September 2014 Abu Muhammad al-Adnani had instructed ISIS loyalists to use vehicles, rocks or knives to slaughter people from France and America.
"If you are not able to find an IED or a bullet, then single out the disbelieving American, Frenchman, or any of their allies. Smash his head with a rock, or slaughter him with a knife, or run him over with your car, or throw him down from a high place, or choke him, or poison him."
He further went on to say that if anyone is unable to come to Iraq or Syria, then then pledge allegiance in your place, pledge allegiance in France," operate within France." Further it was stated, "there are weapons and cars available and targets ready to be hit.Kill them and spit in their faces and run over them with your cars."
al Qaeda too had made a similar call in its magazine 'Inspire'. It had referred to trucks as the ultimate mowing machines. "The idea is to use a pickup truck as a mowing machine, not to mow grass but mow down the enemies of Allah."
