We're learning more about how the driver managed to get the pickup truck onto the street, where usually there are bollards, a reporter at the news conference says.

Mayor LaToya Cantrell says, as we have been reporting, that bollards blocking the street there are undergoing replacement.

Superintendent Kirkpatrick takes over, and tells the room they had patrol cars and other barriers in place instead.

However, she says the suspect "drove around onto the sidewalk and got around" the barriers stationed on the street.

"We did have a car there, we had barriers there, we had officers there, and they still got around."

Kirkpatrick adds that the so-called wedge barrier in that spot was known to have "malfunction problems".

She says these type of wedge barriers can usually be raised and lowered, but they were lowered at the time of the incident as officials didn't want to risk them stuck in the raised position and impeding potential access for emergency vehicles.

Another police official later adds that there had been a vehicle parked where the malfunctioning barrier would usually be.

The governor says officials will review how this played out.

A journalist at the news conference asks about reports that bollards on Bourbon Street were down because of repairs, asking if there was any option to put a police car in its place.

Governor Jeff Landry appears increasingly agitated by the questions, and before passing the microphone over to the New Orleans mayor, replies: "One of the first things I thought this morning, when the mayor called me, I will tell you... that whatever the problem was, is going to be solved".

Mayor of New Orleans LaToya Cantrell says New Orleans police deemed the bollards on Bourbon Street "inefficient" and the government decided to improve them for the Super Bowl this year.

"Bollards were not up... because (their repair is) near completion, with the expectation of being completed of course, by Super Bowl. Way before Super Bowl... that is the reason," she tells the news conference.

FBI official Alethea Duncan confirms the suspected attacker was an Army veteran, saying officials believe he was on discharge but cannot currently confirm this.

The superintendent of police, Anne Kirkpatrick, speaks now.

In the last 24 hours, she says there were approximately 400 police officers in the French Quarter.

"Last night, three of our officers engaged this terrorist who shot at them," she says, and confirms they killed the suspect.

It's already been confirmed that two officers were injured in the exchange of fire.

She says these officers "will be okay" and she has already personally visited them in hospital.

We have just heard from the news conference that the Sugar Bowl, an annual college American football game, has been postponed until Thursday evening because of the mass casualty incident in New Orleans today.

It was due to kick off later today, and would've seen the University of Georgia take on Notre Dame.

Earlier, the University of Georgia's president said one of its students was critically injured in the attack and is receiving medical treatment.

The sold-out event brings in a crowd of around 68,000.

Louisiana Governor Jeff Landry takes over at the news conference, and thanks the first responders, medical professionals and police officers who were on the scene on Bourbon Street.

He says he wants to make public safety a "priority."

They "intend to be transparent about any defects" in the system, so they can be addressed, Landry says.

He adds they have been trying "diligently" to address security concerns ahead of the upcoming NFL Super Bowl in a few weeks' time.

"Ironically," Landry says, he was going to introduce an emergency declaration tomorrow to deal with security around that event, but has now done so today.

This will allow local partners and the federal state to combine resources "to get this city safe."

They are doing "everything that we can to secure [residents' and visitors'] safety in the city."

We're now hearing from the New Orleans mayor, LaToya Cantrell.

She gives her condolences to victims and their families and says the priority continues to be removing victims from Bourbon Street as soon as possible.

She has visited two injured police officers in hospital and says they are doing well.

Federal Bureau of Investigations (FBI) assistant special agent Alethea Duncan is speaking now about the incident in New Orleans early on Wednesday morning.

She says "this is an ongoing investigation that's rapidly evolving."

She then goes over the details we have been reporting from a newly released statement from the FBI.

Officials have found, "as of now", two improvised explosive devices in the area, she says.

Duncan asks for anyone with information or who may have interacted with the suspected driver of the vehicle, Shamsud-Din Jabbar, recently to contact the FBI.

She then says law enforcement does not believe that the suspect was solely responsible for the attack.

We're expecting to hear from officials in New Orleans shortly to give an update on the attack.

Speakers include Louisiana governor Jeff Landry, FBI assistant special agent Alethea Duncan, New Orleans Police Department superintendent Anne Kirkpatrick and Louisiana State Police colonel Robert P Hodges.

Earlier today, Kirkpatrick told residents to avoid the area around Bourbon Street.

The FBI has also released details about its investigation, saying a potential improvised explosive device (IED) and weapons were found in the suspect's vehicle

It adds that "other potential IEDs were also located in the French Quarter" - the historic area of New Orleans where Bourbon Street is located.

Their bomb technicians are working to see if they are "viable" and to make them safe.

The FBI also says the Ford pickup truck "appears to have been rented" and agents are working to confirm how the subject came into possession of the vehicle".

It adds that they are also "working to determine the subject's potential associations and affiliations with terrorist organizations" after finding the Islamic State group flag in the truck.

More from the FBI statement, which says the suspect, Shamsud-Din Jabbar, is a 42-year old US citizen from Texas.

A flag for the Islamic State group (IS) was found in the pickup truck driven into a crowd of people early this morning, according to the FBI.

In a statement online, the FBI confirms 42-year-old Shamsud-Din Jabbar was shot dead at the scene after exchanging fire with law enforcement at the scene.

The pavement bollards on Bourbon Street, from Canal Street to St. Ann Street, which are partly-designed to keep pedestrians safe, were in the process of being upgraded when the attack occurred this morning.

The work involves replacing old bollards with new removable stainless-steel bollards and sidewalk repairs at various locations, according to the Nola government website.

The removable bollards were designed to help close the street to cars during pedestrian-only times, it says on the project website page. , externalThey can be stored away when the street is open to all traffic.

The work has been going on in the French Quarter since November, and is expected to continue until February, the New Orleans government website states.

It's unclear if they were in place where the driver entered Bourbon Street.

In a press conference earlier, police superintendent Anne Kirkpatrick said the suspect had gone around the barricades.

Investigators are looking at whether the suspect was connected to or inspired by a foreign terror organisation, law enforcement and city official sources told CBS News, the BBC’s US partner.

Law enforcement sources said they are exploring whether a black flag which appeared to be attached to the rear bumper of the pick-up truck during the attack could be an flag of the Islamic State group (IS), or potentially tied to another foreign terror organisation.

A person familiar with the investigation told CBS News that at this point, neither IS nor any other foreign terror group had claimed responsibility for the attack.

The suspect accused of driving a truck through a crowd on Bourbon street in New Orleans, killing 10 people and injuring at least 36, has been identified as 42-year-old Shamsud Din Jabbar, according to two federal officials who spoke to the BBC's US partner, CBS News.

The FBI confirmed earlier today the incident is being treated as an "act of terrorism" and the perpetrator was killed after the attack.

We are starting to get more information about the pick-up truck driven into a large crowd in New Orleans in the early hours of New Year's Day.

US federal law enforcement is currently investigating whether the vehicle used in the overnight attack belonged to the suspect, accordint to the BBC's US news partner CBS.

It appears that the suspect may not have owned the truck himself, CBS says, and it may have been stolen, rented or borrowed.

Sources familiar with the investigation told CBS News that the suspect was wearing body armour at the time of the attack.
