An official with the Islamic State group has been detained in Iraq, suspected of being involved with inciting the pickup truck-ramming attack in New Orleans that killed more than a dozen people celebrating the start of 2025, Iraqi authorities said.

Iraqi authorities had received requests from the U.S. to help in the investigation of the attack in the predawn hours of New Years Day in the famed French Quarter of New Orleans, Iraqi judicial officials said.

A U.S. Army veteran driving a pickup truck that bore the flag of the Islamic State group sped down Bourbon Street, running over some victims and ramming others, authorities said at the time. The Federal Bureau of Investigation identified the driver as Shamsud-Din Jabbar, 42, a U.S. citizen from Texas, and said it was working to determine any potential associations with terrorist organizations.

After driving his pickup truck onto a sidewalk around a police car blocking an entrance to Bourbon Street and striking the New Year’s revelers, he crashed into construction equipment, authorities said. He then opened fire on police officers and Bourbon Street crowds, and was shot and killed by the officers, authorities said. Investigators found guns and what appeared to be an improvised explosive device in the vehicle, along with other devices elsewhere in the French Quarter.

Iraqi officials said that Baghdad’s Al-Karkh Investigative Court specified the suspect who was later detained and turned out to be a member of the Islamic State group’s foreign operations office.

The officials, who spoke on condition of anonymity in line with regulations, did not release the name of the suspect, only saying that he is an Iraqi citizen. The officials said the man will be put on trial in accordance with the country’s anti-terrorism law, adding that Iraq is committed to international cooperation in fighting terrorism.

“The FBI’s investigation into the New Year’s Day terrorist attack in New Orleans remains active and ongoing,” the FBI said in a statement Tuesday.

“While we continue to work with our law enforcement partners, both in the U.S. and internationally, based on the information to date, we continue to believe that Shamsud Din-Jabbar acted alone in carrying out the attack on Bourbon Street,” the agency said, saying that anyone with information is encouraged to contact them.
