IS in New Orleans? Trump’s retrenchment may have to hold

Suggestions that the terrorist responsible for New Year attack on New Orleans had links to Islamic State (IS) show that the threat posed by Islamist militants cannot be ignored, even though the world’s attention has been so diverted of late.

The focus for much of the 2020s has been on more conventional conflicts in Ukraine and the Middle East, but events in New Orleans’ French Quarter on New Year’s Day has swiftly altered both the mood and the threat level.

US-born Shamsun-Din Jabbar, 42, who was killed in a shoot-out with police, is the key suspect in the truck attack in the city’s famous Bourbon Street district that killed 15 and injured 30.

Police have now revealed that he had an IS flag on his vehicle and posted pro-IS videos on social media before the attack, in which he used his truck to plough into people celebrating the start of 2025. The truck was also found to contain a potential improvised explosive device (IED).

A Texas-born American citizen and Army veteran who served in Afghanistan, Jabbar was working as an estate agent and is reported to have been in financial difficulty and recently divorced at the time of the attack.

Since the attack, the FBI has reported that other potential IEDs have been found in the southern city’s French Quarter. Pipe bombs with nails and suspected C4 explosives were found in an ice chest left near police cars at the corner of Bourbon Street and Orleans Street, near where the pick-up truck attack took place.

Another pipe bomb was found in a cooler a block away and a third suspected device was discovered in a purple suitcase. Jabbar had been renting accommodation in the neighbourhood of St Roch, two miles from the French Quarter, which investigators found ablaze and laden with bomb-making materials. 

Jabbar was wearing body armour and camouflage fatigues when he emerged from the pick-up truck. US authorities initially considerd a possible military link between Jabbar and the driver in a Cybertruck explosion outside the Trump hotel in Las Vegas which took place just hours later.

Looking at links

The driver of the truck, which was parked outside the main entrance to the hotel and filled with fuel and fireworks, shot himself in the head before the Cybertruck exploded, injuring several passersby. He was also an army Veteran.

Police have since said they now think Jabbar was a "lone wolf", with "no definitive link" between the two suspects, but Las Vegas Sheriff Kevin McMahill said his force were "not ruling (anything) out", adding that there were some "very strange similarities" between the two incidents.

Security has now been increased around locations such as Trump Tower and Times Square. New York City Mayor Eric Adams said: "While there are no immediate threats to our city at this time, out of an abundance of caution, we have heightened security and have increased NYPD presence at relevant locations."

It is not clear whether both drivers overlapped in the time or locations they served in the military, but some US media reports say they served at the same military barracks, and police say they used the same car-sharing app to rent the vehicles used in the attacks.

Louisiana Attorney General Liz Murrill, who is overseeing the investigation into the New Orleans attack, said there was reason to believe that multiple individuals were involved and vowed the strongest response. "In Louisiana, we have the death penalty, and we will carry it out!" she wrote on X.

Effect on policy

US President Joe Biden condemned the "despicable" act, noting how Jabbar had "expressed the desire to kill". For US President-elect Donald Trump, who takes over from Biden this month, the re-emergence of IS as a threat on home soil could have a profound impact on his administration's approach to national security.

During his first term, Trump played a prominent role in the US-led coalition effort to destroy IS in the Syrian city of Raqqa. With the overthrow of the Assad regime in Damascus last month, there are fears of a resurgence of IS-inspired terrorism, with cells said to be taking advantage of Syria's current lawlessness to regroup.

Trump, who has been highly critical of Biden's handling of the conflicts in Ukraine and the Middle East, said the response of US law enforcement to New Orleans and Las Vegas was "ineffective", accusing the FBI and the Department of Justice of "not doing their jobs" in protecting Americans, which had turned the country into a "laughing stock".

Posting on social media, he said: "The USA is breaking down - A violent erosion of safety, national security, and democracy is taking place all across our nation… Only strength and powerful leadership will stop it."

Trump has said he wants to reduce Washington's involvement in global conflicts, but if, as seems likely, IS was behind the New Orleans attack (and possibly the Las Vegas attack, too), he may not be able to turn his back just yet.
