—We’re live-blogging the major updates. All updates are in Eastern Daylght Time (GMT -4).


July 21 at 1:12 p.m.

Paris prosecutor Francois Molins gave new details about the attack's planning Thursday, saying it had been in the works for months and that five alleged accomplices were in custody. The Los Angeles Times has more:

Molins' office, which oversees terrorism investigations, opened a judicial inquiry Thursday into a battery of charges for the suspects, including complicity to murder and possessing weapons tied to a terrorist enterprise.

The suspects are four men — two Franco-Tunisians, a Tunisian and an Albanian — and one woman of dual French-Albanian nationality, Molins said. The driver was a Tunisian man who had been living in Nice for several years.

People close to Bouhlel said he had shown no signs of radicalization until very recently. But Molins said information from Bouhlel's phone showed searches and photos that suggested he could have been preparing an attack as far back as 2015.


July 18 at 10:21 a.m.

Prime Minister Manuel Valls was booed by crowds Monday during a memorial service on Nice’s Promenade des Anglais. Some in the crowd yelled “murderer,” others shouted for him to resign before the minute’s silence, which was marked across the nation. There’s much frustration in France following the Nice attack, the third major terrorist attack in France since January 2015. Valls and French President Francois Hollande were also booed Friday during a visit to the site of the attack.

Meanwhile, French authorities announced the arrest of an Albanian couple Sunday in connection with Nice attacker Mohamed Lahouaiej Bouhlel, said Agnes Thibault Lecuivre, a spokeswoman for the anti-terrorism prosecutor. They are among six people detained following the attack—three of who were transferred to the SDAT, France’s counterterrorism task force.

Bouhlel’s estranged wife was also arrested in connection with the attack, though she was released Sunday morning. Her attorney told CNN that she hadn’t had contact with him as they were in the midst of divorce proceedings. The couple have three children.

French Interior Minister Bernard Cazeneuve said investigators have yet to establish a link between the attacker and ISIS, which claimed responsibility for the attack Saturday.


July 16 at 6:45 a.m.

The Islamic State claimed responsibility for the attack via it Amaq news agency. It said the attack was carried out by a “soldier of the Islamic State.” Here’s more from the SITE intelligence group, which monitors ISIS and other groups:


3:07 p.m.

President Obama, speaking at the White House Friday, pledged to stand with France, saying terrorism “is a threat to all of us.” Recognizing the harm that single individuals can have, he told a group of diplomats at a reception in the East Room that the world must be vigilant against ISIS, and that together, “We are going to destroy this vile terrorist organization.”

It’s worth pointing out that no one has yet claimed responsibility for the attack.

Obama again cautioned against grouping all Muslims together after these attacks.

“We cannot give in to fear or turn on each other,” he said. “We cannot let ourselves be divided by religion.”


1:50 p.m.

Francois Molins, the Paris prosecutor, also provided details of what exactly happened Thursday night in Nice. The attacker, he said, rented the truck on July 11 and was scheduled to return it July 13.

Here’s more from the Guardian:

He drove about 2km down the promenade, and fired repeatedly at three policemen when they confronted him near a hotel. Gun shots were exchanged but the truck continued for 300m – the police “eventually found the driver dead in the passenger seat”, the prosecutor says.

In the cabin was one automatic firearm, a charger, bullets, as well as a second automatic weapon. There were also two Kalashnikovs and M16s, also firearms, one grenade, one mobile telephone, and various documents which are still being examined. “We also found a driver’s card and and a card under the name”

He was born on 3 January 1975 in Tunis with residence in Nice, he says. The gunman was “a chaffeur and deliveryman”. “His ex-wife was detained at 11am this morning.”

Many of these facts were reported earlier by French news organizations using anonymous sources; they are now being publicly confirmed.


12:57 p.m.

President Obama has ordered all flags at the White House, public grounds, and buildings across the country, and federal and military buildings abroad lowered to half-staff to honor the victims of the terrorist attack in Nice until July 19. The flags were recently lowered for the shooting in Dallas last week.


11:20 a.m.

President Obama will address the attack in Nice at an event at the White House Friday at 3:10 p.m. There, he is hosting the Diplomatic Corps Reception in the East Room. We’ll report on his comments here.


11:12 a.m.

Francois Molins, the Paris prosecutor, held a news conference in which he said 10 children were killed in the Nice attack.

He said “202 people were injured, including 52 who are now in critical care.” Of these 52, he said, “25 are still in intensive care.” The numbers, Molins added, are preliminary.

Here’s more (via the Guardian):

The terrorist who drove the truck as you know was shot to prevent him from committing more criminal action.

They have managed to neutralize this person, thus avoiding further victims. I would also like to pay tribute to all state services who were mobilized following this attack.

He also, the BBC reported, confirmed the identity of the driver. The name is the same as those being reported earlier: Mohamed Lahouaiej Bouhlel, a 31-year-old French citizen of Tunisian origin.

Authorities have raided Bouhlel’s home in Nice in search of evidence.


10:46 a.m.

The Tour de France will continue Friday, despite the attack in Nice. The cycling race, now in Stage 13, passes through the south of France from Bourg-Saint-Andéol to Caverne du Pont d'Arc, three hours west of the deadly incident.

There was a moment of silence before the racing began Friday. Christian Prudhomme, the race’s organizer, explained why the race would go on:

We wondered about having a race today or not. But in agreement with the state authorities, we believe that the race must go on and we shouldn’t give in to the pressure of people who would like us to change our lifestyle.

The Tour de France will go on in sobriety and dignity.

Thousands of fans came out to cheer on cyclists, as event security continues to stay vigilant.


10:40 a.m.

The French health ministry says 188 people were hospitalized after the attack. Of these, it said, 48 are in a state of “absolute urgency.” Earlier Friday Hollande said 50 people are “between life and death.”


9:34 a.m.

Leaders from across the Arab and Muslim world are condemning the attack. The Gulf Cooperation Council (GCC) said its stands in solidarity with France and the victims of Thursday’s attack. The GCC’s secretary general, Abdullatif bin Rashid Al-Zayani, called it a “criminal and cowardly incident whose perpetrators were stripped from all moral and human values.” Al-Azhar, the leading Sunni Islam center of learning in Cairo, called the attacks vile, and said that it, “affirms the importance of uniting efforts to eliminate terrorism and rid the world of its evil.”
Saudi King Salman also said his country joined in “the rejection of terrorism in all its forms and manifestations and the importance of international efforts to confront and eliminate it.” Ahmed Gheit, chief of the Arab League, called the incident a “craven terrorist attack.”


9:28 a.m.

French President Francois Hollande, flanked by Prime Minister Manuel Valls and Marisol Touraine, the social-affairs minister, is speaking in Nice. He said many foreign nationals and children are among the dead. He says at least 50 people are injured. He also thanked the police officers who responded to the attack and killed the truck driver.

His remarks in English (via the BBC):

There are 50 other people who are still receiving emergency treatment. They are between life and death. Amongst the victims are French citizens, as well as foreigners, who came from all continents. And there are a number of young children who came to watch fireworks with their families, who have been struck down just to satisfy the cruelty of one individual or [possibly] of a group.


9:06 a.m.

Interpol says it is sending a team to Nice to help with identifying the victims of the attack.


8:37 a.m.

Family members of the two Americans killed in Nice have identified them as Sean Copeland, 51, and his 11-year-old son, Brodie. They were on a European vacation the Austin American Statesman reported. The family, in a statement, to the newspaper:

We are heartbroken and in shock over the loss of Brodie Copeland, an amazing son and brother who lit up our lives, and Sean Copeland, a wonderful husband and father. They are so loved.

Another family member posted on social media:


8:21 a.m.

Several news organizations are naming the truck driver who drove his vehicle into the crowds in Nice. We are not naming the man because he has been identified through the ID found in the truck—not yet via DNA evidence. He is being described as a 31-year-old French-born Tunisian, a petty thief who was known to authorities. French news reports say authorities have raided the man’s home in Nice. We’ll provide more information on this aspect of the story when officials publicly confirm the man’s identity.


8:10 a.m.

We’re learning more about the nationalities of the victims of the attack. The Swiss Federal Office of Police said a Swiss citizen was among the dead. It did not provide other details, though Swiss news reports have named a woman as the victim. The Armenian Foreign Ministry said two Armenian citizens were also killed. The Russian Foreign Ministry said at least one Russian was killed in the attack. These numbers are in addition to the the two Americans the U.S. State Department said were killed.


7:34 a.m.

Several European countries announced Friday security measures, including the tightening of their borders with France, following the attack.

The German Federal Police said: “In coordination with the French security authorities, the federal police are strengthening their control in the area of cross-border traffic into France.”

Spain increased security along its more than 400-mile border with France and put in place additional steps. Italian Interior Minister Angelino Alfano said his country would boost measures along the border, as well. Belgium, which was targeted in deadly attacks by militants in March, said security would be increased ahead of its own National Day celebrations, held July 21. In London, Mayor Sadiq Khan said the U.K.’s capital would review its security measures following the attack.

The mood in Nice, and indeed around the world this morning, is summed up by this man who was photographed Friday along the city’s waterfront.

7:13 a.m.

Among the dead are two Americans, the U.S. State Department said, without naming them. BuzzFeed News has named two Americans, a man and his 10-year-old son from Austin, Texas, as among those killed. It cited a relative, as well as the local baseball league. It’s unclear if the State Department’s toll refers to the same people being named by BuzzFeed.


5:23 a.m.

Overnight, the Interior Ministry raised the death toll from 80 to 84.

Several witnesses have said the truck driver drove at a high speed, zigzagging through the crowds. These accounts have not been independently confirmed.

It’s also worth reiterating that no one has officially yet claimed responsibility for the attack, though it was certainly celebrated on jihadist websites, including those linked to the Islamic State.

Several French news organizations, as well as Reuters, are identifying the driver of the truck as a French-born man of Tunisian origin. He was 31 years old and known to police for petty crimes, they reported, citing unidentified sources. Investigators are working to determine if he was working alone.


5:16 a.m.

Manuel Valls, the French prime minister, said starting Saturday France will observe three days of mourning. Here are his comments (the translation’s from the BBC):

Times have changed and we should learn to live with terrorism. We have to show solidarity and collective calm. France has been hit in its soul on 14 July, our national day. They wanted to attack the unity of the French nation. The only dignified response is that France will remain loyal to the spirit of 14 July and its values.

“France,” he added, “will not allow itself to be destabilized.”

He also said the Paris prosecutor’s office was in charge of the investigation.

9:40 p.m.

9:31 p.m.

News of the Nice attack is dominating the Friday editions of the French newspapers.

Here’s Le Figaro:


9:27 p.m.

Hillary Clinton, the presumptive Democratic presidential nominee, told CNN: “Clearly, what is happening is terrorist groups are seeing that they have opportunities inside France for both home-grown terrorism and importing terrorists.” She added:

Assuming this was a group like ISIS or somebody who is sympathetic to ISIS, whether they have had any direct contact with the organization, from everything we have learned about what’s happening in Iraq, there have been a number of victories on the battlefield recently by Iraqi forces and coalition partners against ISIS. they are losing territory and yet, that does not seem to have any impact on the number of attacks we’re seeing in other countries. if anything, it seems like those attacks are escalating. … But i think it’s also clear that as a result, of these advances against ISIS, and their main headquarters in Raqqah, their urgent desire to inflict terrorist attacks elsewhere has led them to accelerate, reaching out not only directly but indirectly through the radicalization online.

It’s worth pointing out here that no one has yet claimed responsibility—nor have French officials publicly described it as a terrorist attack.


9:24 p.m.

Several witnesses have come forward to describe what they saw tonight in Nice.

Hali McField of Fort Lauderdale, Florida, told CBS News, said she “watched a bunch of people running away” from the scene, screaming. Wassim Bouhlel, a Nice native, told the AP, he saw the truck drive into the crowd. “There was carnage on the road,” he said. “Bodies everywhere.”

Colin Srivastava, a Briton, told the BBC he saw several hundred people running toward him “looking panic-stricken.” He ran along with them, he said, until the police came by and said: “Run, now.”

Katie Shaw, an Australian tourist, told the Australian Associated Press: “We had no idea what was going on. Then all we could hear was gunshots. My friend just grabbed me and we all went out the back stairs and had to sprint out staying low with guys ushering us away from the foreshore.”
