Suspect was pictured in New Orleans before attack - what else do we know?

New surveillance photos released by the FBI allegedly show the perpetrator of a deadly attack walking the streets of New Orleans, Louisiana, before he drove a truck into a crowd, killing fourteen people.

At least 35 more were injured after the man carried out an Islamic State (IS)-inspired attack in New Orleans' busy French Quarter during the early hours of New Year's Day.

Here's what we know so far about what happened and the perpetrator, who was killed in the incident.

At 03:15 local time on New Year's Day, a pick-up truck ploughed into crowds gathered on Bourbon Street - known globally as one of the largest places for New Year's Eve parties - in the heart of New Orleans' French Quarter.

CCTV footage shows a white Ford pickup truck racing onto the pavement to get around a police car before hitting pedestrians. The attacker then got out of the car and began firing at police officers, injuring two. He died following the gunfight with three responding officers, the FBI said.

Police described the act as "very intentional", adding that the assailant - identified as Shamsud-Din Jabbar - was "hell-bent on creating the carnage and the damage that he did."

Whit Davis, from Shreveport, Louisiana, told the BBC that he was held in a bar with a large group in the aftermath of the attack while police secured the scene.

When they left, they "were walking past dead and injured bodies all over the street", he said.

Law enforcement sources told ABC News that Jabbar placed explosive devices in the area before changing clothes and then carrying out the attack. The FBI released a photo that officials say shows a cooler containing an improvised explosive device (IED).

Officials have said it was not clear whether Jabbar ever tried to detonate two explosive devices that he brought in coolers before the vehicle attack or whether they malfunctioned.

The FBI said Jabbar, 42, an Army veteran and US citizen born in Texas, as the attacker.

The vehicle he was driving during the attack was electric and rented from the platform Turo, known as an "Airbnb of cars". The company confirmed Wednesday, with a "heavy heart", that the vehicle was one of theirs.

During his drive from Houston to New Orleans, he posted videos online in which he professed his support for IS, authorities said.

Jabbar was brought up in Beaumont, a city in eastern Texas near the Louisiana border. He was raised Muslim but left the religion for many years and only recently returned to his faith, his brother told the BBC's US partner, CBS News.

"Then he came back into it, maybe just this time around, he was gonna take it a little more seriously," Abdur Rahem Jabbar told CBS.

According to a now-removed LinkedIn profile, Shamsud-Din Jabbar worked in various roles in the US Army, including in human resources and IT, before he was discharged in 2015. He was deployed to Afghanistan from February 2009 to January 2010. His most recent address was in Houston.

He studied at Georgia State University from 2015 to 2017, graduating with a degree in computer information systems.

Accountancy firm Deloitte confirmed that Jabbar was hired by the company in 2021 and he reportedly also worked for Ernst & Young.

The suspect was married three times and has children from two relationships. His first marriage ended in 2012, and his second lasted from 2013 to 2016. He married once again in 2017 before divorcing in 2022.

Court records relating to Jabbar's most recent divorce point to financial difficulties – with his monthly expenses, including child support, exceeding his income.

Separate documents reveal that his then-wife had accused him of financial mismanagement and had obtained a temporary restraining order against him.

Jabbar also appears to have worked in real estate – holding a licence that expired in 2023. He had a criminal record, relating to traffic offences and theft.

Jabbar's brother told local Houston news outlet KPRC that his family was shocked by the incident and that their hearts go out to the victims.

"We're all grieving about this," he said. "This wasn't the man I knew. This wasn't the father, the son, that I knew. And also, this isn't any representation of Islam, or Muslims or the Muslim community."

Jabbar's brother also said he has spoken to the FBI and officials asked him how he would describe his brother and the type of person he was. He told them he did not pick up any hints that his brother might commit a terror attack.

The authorities had been investigating whether Jabbar had accomplices, but later clarified that they were confident he acted alone.

FBI deputy assistant director Christopher Raia said officials had recovered three mobile phones and two laptops that belonged to Jabbar, which were being examined by FBI specialists.

President Joe Biden said he had been briefed by the FBI and that the suspect uploaded videos to social media "mere hours before the attack".

In one of the videos Jabbar posted on the drive, he said he initially intended to harm his family, but decided against it, believing it would not have illustrated the "war between the believers and the disbelievers".

Jabbar said in the videos that he joined IS before the summer and offered a will and testament, Mr Raia said.

Investigators also are looking at whether the attack in New Orleans is linked to the explosion of a vehicle outside the Trump Hotel in Las Vegas, which killed the car's driver and injured seven others.

Biden said "they have not found any evidence of such a connection" between the incidents.

Police said it appears that the victims were mainly locals from New Orleans, even though many tourists were visiting for New Year celebrations and the Sugar Bowl – part of the American football college playoffs – which was postponed to Thursday following the attack.

Raia clarified that the death toll previously given as 15 included the attacker. It now stands at 14 victims.

Among the dead is former Princeton University American football star Martin "Tiger" Bech, his mother Michelle confirmed to CBS News.

"He was a 'Tiger' in every way - a ferocious competitor with endless energy, a beloved teammate and a caring friend," Bob Surace, Princeton's head football coach, said in a statement.

Aspiring nurse Nikyra Cheyenne Dedeaux's death was confirmed by her mother, Melissa, on social media.

She told local media that the 18-year-old had snuck out that evening with a cousin and friend, who both survived the attack.

Hubert Gauthreaux, 21, was identified as one of the dead by his former high school, Archbishop Shaw, in Louisiana. Just after ringing in the new year, he texted his family: "I love you."

Store manager and father of two Reggie Hunter, 37, was described by his cousin Shirell Robinson Jackson as "full of life".

Ms Jackson told CBS that Mr Hunter had been with another cousin, who was injured in the attack.

Nicole Perez, 27, worked at a deli and was mother to a four-month-old. Her friend and boss, Kimberly Usher Fall, said she was a dedicated, smart and "good-hearted person".

Audio-visual technician Matthew Tenedorio, 25, had a "laid-back spirit and infectious laughter" that brought joy to those around him, according to a fundraiser his family set up in his name.

Kareem Badawi, a University of Alabama student, was identified by his school. On Facebook, the university's president Stuart Bell wrote that he grieves "alongside family and friends of Kareem in their heart-breaking loss".

Drew Dauphin's mother confirmed his death in a statement to CBS News. The 26-year-old worked at a lab in Auburn University, who said he always bought a "positive attitude."

Through tears, Billy DiMaio's father told the Washington Post there was "no one like him" and that the 25-year-old "was one of a kind." He said he had just earned a promotion in his role at the podcast and radio company Audacy, which also confirmed his death.

New Orleans native Terrence Kennedy, 63, was killed in the attack, according to his wife, Jacqueline, who told CBS News she identified his remains on Thursday.

Bourbon Street is a well-known nightlife and tourist hotspot that is filled with restaurants, bars and clubs with live music.

It is within New Orleans' French Quarter, a lively area that attracts tourists and locals, especially to celebrate New Year.

It was established by the French – who colonised the state of Louisiana before the founding of the US – in 1718. The original grid of streets designed back then is at the heart of what draws visitors to the city.

Every year, upwards of a million people flock to its famous Mardi Gras carnival and parade in the spring, famous for the strings of colourful beads worn by partygoers.

The city's famous jazz music paused on Thursday afternoon at the rescheduled Sugar Bowl football game. The tens of thousands of fans in the stadium for the annual university game held a moment of silence for the victims before kick-off.
