Israeli leaders condemned the horrific Nice terror attack and offered their support to the French people in solidarity.

At least 84 people have been killed and 200 wounded when a truck ran into a crowd celebrating France’s national daya long the Promenade des Anglais beachfront.

President Reuven Rivlin sent on Friday morning a letter of condolence to French President Francois Hollande.

Rivlin wrote, "It is with pain and sorrow that I must once again write and express my deepest condolences, and those of all the Israeli people, following the horrific terror attack in Nice."

He added that "Israel stands with France and the Israeli people stand with the French people, shoulder to shoulder in the face of this terrible evil, as should the whole free world. We must work united to reach the terrorists, their supporters and backers, wherever they may hide. "

Isaac Herzog, leader of the Zionist Union opposition said : "The vile terrorism has returned in full force and destroyed the celebration of freedom, equality and fraternity."

"This is our generations world war. my condolences to the French nation and the families of the killed and wounded."

Israel's former president Shimon Peres said "we embrace the French people who are suffering from this tragic terror attack."

He added that "world leaders must come together and fight global terrorism."

Israeli media reported that five Jewish residents of Nice were lightly hurt in the attack.

A statement from the Haredi group Chabad identified one of the wounded by his Hebrew name, traditionally used in prayers for his recovery, as Moshe ben Yaakov.

“Counselors for Chabad’s Gan Israel day camp were also at the scene of the attack, having apparently crossed the street just moments beforehand, they narrowly missed the truck’s path of destruction,” said Chabad spokesman Rabbi Motti Seligson, in an email.

In the US, presumptive Republican presidential nominee Donald Trump expressed condolences for the victims of the attack and postponed the announcement of his running mate.

"In light of the horrible attack in Nice, France, I have postponed tomorrow's news conference concerning my Vice Presidential announcement," Trump said in a Fox News interview. "We will announce tomorrow when it will be."

Trump, who has proposed banning Muslims from "terror states" from entering the United States, said in another Fox News interview that the attack in France showed the United States and the rest of the world needed to get tougher in the fight against Islamist militants.

"This has to be dealt with very harshly," Trump said.

Hillary Clinton, Trumps Democratic rival, also condemned the attack stating that "once again, it appears the terrorists have struck at one of our closest allies in Europe," adding that "Every American stand in strong solidarity with the people of France, and we say with one voice: we will not be intimidated."
