A man intentionally drove a pickup truck into a crowd of revelers on Bourbon Street in New Orleans’ French Quarter early on New Year’s Day, killing at least 15 people and injuring dozens of others, officials said, according to CBS.

A black ISIS flag was flying from the truck’s rear bumper, and the attack is being investigated as an act of terrorism, the Federal Bureau of Investigation said. 

The man driving the vehicle has been identified as Shamsud-Din Jabbar, 42, a U.S. citizen from Texas, the FBI said. 

In televised remarks Wednesday evening, President Biden said the FBI has determined that just hours before the attack, Jabbar “posted videos to social media indicating that he was inspired by ISIS, expressing a desire to kill.”

The vehicle was an electric Ford pickup truck that appears to have been rented, the FBI said. Texas Lt. Gov. Dan Patrick said on social media Jabbar rented the truck on Dec. 30, while living in the Houston area, before heading to New Orleans.

FBI special agent Alethea Duncan said at a news conference Wednesday afternoon that investigators “do not believe that Jabbar was solely responsible” for the attack, and the FBI believes he may have had help carrying it out. Duncan said the FBI is looking at a “range of suspects” and does “not want to rule anything out” at this stage of the investigation. The FBI is also working to determine his potential affiliations or associations with terrorist associations. 
A person familiar with the investigation told CBS News that at this point, neither ISIS nor any other foreign terror organization has claimed responsibility for the attack. 

The attacker drove around barricades and up onto the sidewalk of Bourbon Street, New Orleans Police Department Superintendent Anne Kirkpatrick said, avoiding barriers that had been placed by police. Kirkpatrick said the man “was trying to run over as many people as he could.” 

“We had a car there, we had barriers there, we had officers there, and he still got around,” Kirkpatrick said. 

The man then exited the car and opened fire on officers, the FBI official said. He died after exchanging gunfire with three responding officers, the FBI said. He was struck by police fire and declared dead at the scene, the New Orleans Police Department said. Two police officers were hit by gunfire but were in stable condition. 

Weapons and two potential improvised explosive devices, or IEDs, were located in the vehicle, Duncan said. At least one other IED was found in the French Quarter, and was detonated by law enforcement, a person familiar with the investigation said. The number of IEDs left behind is a large part of why the FBI believes the man may have had an accomplice, sources tell CBS News. Investigators are combing through video to see if there were accomplices involved in placing the devices, sources told CBS News. 

Further sweeps by law enforcement did not find any more IEDs, Duncan said. Kirkpatrick said police walked the area as a grid, looking for any suspicious items. Anyone who sees anything suspicious should contact officials, Duncan said. 

A long gun was recovered from the scene, law enforcement sources told CBS News. The long gun had a “suppressive device” on it that acted as a silencer, according to sources on the scene. 

Two sources familiar with the investigation told CBS News the man was wearing body armor. 

Investigators from the FBI, Homeland Security and bomb squad have all been on the scene at an Airbnb in the St. Roch area of New Orleans, where officials tell CBS News the suspect was staying while in New Orleans. That building caught fire on Wednesday and the investigation into that fire is ongoing.

Duncan asked that anyone with information about the man contact the FBI. A U.S. official confirmed to CBS News that he had previously served in the U.S. military. 

Louisiana Gov. Jeff Landry called it “a horrific act of violence” and said he and his wife were “praying for all the victims and first responders on scene.” He urged people to avoid the area. 

“As of now, 15 people are deceased. It will take several days to perform all autopsies. Once we complete the autopsies and talk with the next of kin, we will release the identifications of the victims,” New Orleans Coroner Dr. Dwight McKenna said in a statement.
