The man responsible for the New Year's Day attack in New Orleans that left 10 dead and more than 30 people injured was carrying an ISIS flag.
Shamsud-Din Jabbar, 42, was identified as being the man who drove a truck down Bourbon Street, intentionally running down pedestrians.
He is a U.S. Army veteran, official confirmed at a Wednesday afternoon news conference.
The FBI is looking into any possible associates of Jabbar's as well as looking into his political and religious views and whether he has ties to any terrorist organization.
The FBI has confirmed that they are investigating the event as a potential terrorist action. So far, two suspicious packages have been detonated by authorities.
Weapons and IEDs were also found in his rented vehicle.
Jabbar was killed in a shootout with police that left two officers injured. The officers are described as being in stable condition.
Authorities are investigating Jabbar's travel history and background. Law enforcement confirmed to NBC that they were also investigating multiple suspected improvised explosive devices linked to the attack.
