Early New Years Day terror struck New Orleans as a man drove a pickup truck into a crowd on Bourbon Street, killing at least 15 and injuring dozens more.
The driver was identified as Shamsud-Din Jabbar, who is believed to have not worked alone.
The attack has prompted investigation from the FBI, calls for senior officials in the Biden administration to testify to the Senate and an address from President Biden.
Here is what we know about the attack so far:
Driver a U.S. citizen
Shamsud-Din Jabbar is a U.S. citizen from Texas who served in the army.
The 42-year-old had an ISIS flag on him at the time of the attack and other associations to terrorist groups are under investigation by the FBI.
The man died in a firefight with police after the attack occurred.
Authorities don’t think he acted alone
Authorities think Jabbar did not act alone in the attack and are investigating other involved subjects.
FBI Houston and the Harris County Sheriff’s Office are currently “conducting law enforcement activity” in north Houston on a block they believe is connected to the attack in New Orleans.
“Due to the ongoing nature of the investigation, no further information can be provided,” the statement reads.
A state police bulletin, according to The Associated Press, showed officials have found surveillance footage during the attack that showed three men and one woman setting up improvised explosive devices.
During a news conference, Louisiana Gov. Jeff Landry (R) was asked how authorities were confident there were multiple people involved, which he responded, “Why would we tell you?”
Incident being investigated as a terror attack
The FBI is leading the investigation and determining if the event was an “act of terrorism.”
“My heart is broken for those who began their year by learning people they love were killed in this horrific attack,” U.S. Attorney General Merrick Garland said, “and my prayers are with the dozens who were injured, including the New Orleans Police Department Officers who risked their lives to save others.”
Garland said “every available resource” will be used in the investigation.
Sugar Bowl postponed
The Sugar Bowl football game was postponed as the stadium was only a mile away from where the attack occurred.
The Caesars Superdome was locked down on Wednesday for a security sweep before the 24 hour postponement of the game was announced.
“Speaking of which, we were scheduled this evening to have a CFP quarterfinal played in the Superdome at 7:45. We have been in consultation with ESPN and the College Football Playoff, the Southeastern Conference, the University of Georgia, Notre Dame. All parties agree it’s in the best interest of everyone in public safety that we postpone the game for 24 hours,” Sugar Bowl CEO Jeff Hundley said.
“There will be more details on that in the coming hours, but for now, that’s the plan we are going to move forward and play the game. We reiterate our thanks to everyone up here for the important work they do up here,” he added.
