Here’s what we know about the truck attack in Nice

A large truck plowed through a crowd of people celebrating Bastille Day in the French city of Nice, killing at least 84 people, according to French authorities, who are investigating the incident as a terrorist attack.

What happened?

• Reports started to emerge around 10:30 p.m. that a truck had crashed into a crowd in Promenade des Anglais, near Nice's Palais de la Mediterranee.
• Some witnesses said they heard gunshots and explosions, but there was confusion because fireworks were being set off at the time of the crash.
• Witnesses described mass panic as hordes of people began to flee in all directions. “It was like the running of the bulls,” said Michael Bordieri, a New Yorker vacationing in Nice, referring to the annual event in Pamplona, Spain, where throngs of people run in front of bulls on a course of a sectioned-off area of a town's streets. 
• Witnesses said a white truck plowed into the crowd, moving at 25 to 30 mph.

Who committed the attack?

• At a press briefing, French prosecutors identified the truck driver as Mohamed Lagouaiej Bouhlel, born in the Tunisian capital of Tunis on Jan. 3, 1975.
• Prosecutors said Bouhlel rented the refrigerated truck on July 11 and it should have been returned by July 13.
• Bouhlel drove about a mile (2 km) down the promenade. He exchanged gunshots with police. He was eventually killed, found dead in the passenger seat of the truck, according to French prosecutors.
• Among the arsenal of weaponry found inside the truck were two automatic weapons, two Kalashnikovs, M16s, a grenade and bullets. Authorities also found a driver’s license and an ID card bearing Bouhlel’s name. A bicycle was also discovered in the truck.
• Authorities were able to positively identify Bouhlel from his fingerprints.
• Bouhlel’s ex-wife has been detained, according to French prosecutors.

What else do authorities know about the attacker?

• According French prosecutors, Bouhlel, 41, was a chauffeur and deliveryman. He was known to police and had a criminal record for “threats, violence and petty theft.”
• According to media reports, citing French prosecutors, Bouhlel  was detained on March 23, 2016, and sentenced to six months for a crime. He had been convicted of “voluntary violence with weapon” in January 2016, according to the reports. 
• French prosecutors said they were not aware that Bouhlel had ever shown any signs of radicalization.

How many casualties?

• At least 84 people are reported dead in the attack in Nice, according to French officials. Ten of them were children, including 11-year-old Brodie Copeland of Texas. He was on vacation in France with his father, Sean, who was also killed. 
• 202 people have have been injured, 52 of them critically. Twenty-five of the injured are still in a coma, prosecutors said. 

What we don’t know

• It’s not clear whether the truck driver acted alone or had accomplices.
• French officials characterized the events as a "terrorist attack." But there has been no claim of responsibility, and it is not known whether the attack was motivated, inspired or carried out by a terrorist organization. The Paris anti-terrorism prosecutor's office has taken charge of the investigation.
