LIVE BLOG: Bastille Day attack in Nice

Marine Le Pen, leader of France's far-right National Front party, on Friday condemned the French government for not doing enough to prevent attacks such as the deadly assault in Nice last night.

"Nothing that we proposed has been implemented," she told French daily Le Figaro.

"Given the new nature of opportunistic terrorism - that is, terrorism without a hierarchical structure - it is essential that we tackle the ideology that underlies these acts.

"In this area, absolutely nothing was done: stripping of citizenship, closing Salafist mosques or prohibiting certain organisations [hasn't been done].

"In truth, we are not at war. For now we are in a war of words."

Le Pen also accused the French government of having little desire to lead the fight against "Islamic fundamentalism.

"This is enough! We need action!"

Tunisia on Friday morning condemned the "cowardly attack" that killed at least 84 people in Nice on Thursday.

President Beiji Caid Essebsi called for "solidarity" in a statement, and expressed "condolences to France and its people".

"Tunisia reiterates its full support for France in its efforts to fight against the scourge of terrorism," he added.

The chief suspect in the attack, named by local media as Mohammed Lahouaiej Bouhlel, is thought to have been born in Tunisia, and was a resident of Nice.

Tunisia's ambassador in France, Mohammed Ali Chihi, said on Friday that the nationality of the victims had not yet been confirmed, and he could not be sure whether any Tunisians were among them.

The French-Tunisian suspect was shot dead by two members of the French special forces after he opened fire on them, police have said.

Brendan Cox, the husband of the late Jo Cox, sent a message of hope and unity to those grieving in the aftermath of the Nice terror attacks. 

At the funeral of his late wife, Cox called for people "not to fight hate with hate." 

London mayor Sadiq Khan has announced that he will "review security measures" in the capital following Thursday night's attack in Nice.

Speaking during a press conference at Gatwick Airport just outside the city, Khan said that he wants to "reassure Londoners".

"We will now review our security measures after the attack. The police chief and I will do everything possible to ensure the safety of Londoners," he said

Fifty four children are among over 100 people taken to hospital after Thursday night's attack, Le Figaro reports.

At least 18 of those injured have severe, life-threatening injuries.

Germany on Friday tightened controls along its border with France in the aftermath of last night's attack.

"In consultation with the French authorities, the federal police will reinforce controls in the areas of cross-border traffic," a statement issued by the German police read.

Thursday night's deadly attack in Nice could have been prevented if "all measures had been taken," the mayor of Bordeaux said on Friday.

Veteran politician Alain Juppe, who has served as Bordeaux mayor since 2006, told Europe 1 radio that France "must be vigilant at all times.

"We are perhaps the number 1 target for Islamic State," he said. There has as yet been no claim of responsibility for the attack.

Juppe said he believes that, "if all measures had been taken, the attack in Nice would not have happened".

Juppe also called for more stringent controls to be placed on school pupils in France, saying that teachers should be allowed to "sanction" pupils if they question "historical truths".

The attack in Nice has provoked clashing responses on Arab social media.

Some expressed their sorrow and dismay, while others expressed anger at percieved double standards over who the international community deems worthy of mourning.

The man suspected of killing at least 84 people on Thursday night before being shot dead by police has been named by local media as Mohamed Lahouaiej Bouhlel.

The suspect's name was first reported by local newspaper Nice Matin, which cited local sources.

Bouhlel was reportedly a resident of Nice - police had previously said that the suspect was a Tunisia-born 31-year-old Nice resident.

French Prime Minister, speaking from the Elysees Palace in Paris, on Friday morning announced three days of national mourning beginning on Saturday.

"We will not give way to the terrorist menace," he said. "France has suffered another flesh wound."

There is no legal definition for what public mourning in France means, but Valls said that flags will be flown at half mast around the country.

The man suspected of killing at least 84 people in Nice on Thursday night parked on the seaside street for nine hours before ploughing into crowds of revellers over a two-kilometre stretch, French media are reporting.

The man, a 31-year-old born in Tunisia but resident in Nice, was reportedly questioned by police, but told them he was there to deliver ice cream.

According to police sources who spoke to Le Figaro, the attacker was convicted of a violent offence in March.

France's parliament will vote on whether to extend the current state of emergency for a further three months on Thursday after two days of discussion.

The state of emergency, which gives police and security services greater powers of arrest, has been in place since November 2015 when gunmen and bombers killed 130 people in a series of attacks in the capital Paris.

Competitors at the Tour de France held a minute's silence ahead of the start of Friday's stage.

British cyclist Chris Froome, who is currently leading the race, sent his condolences to the people of Nice following the attack.
