The bulletin was sent out of an abundance of caution to sensitize law enforcement around the country to be on the lookout for any activity pointing to the use of vehicles as a method to inflict mass casualties, sources told ABC News. "We advise federal, state, local, tribal, and territorial government and law enforcement officials and private sector security partners to remain vigilant of potential copycat or retaliatory attacks inspired by this attack and other recent, lethal vehicle-ramming incidents across the globe," the bulletin sent by law enforcement and obtained by ABC News said. The bulletin notes that ISIS -- to which New Orleans suspect Shamsud-Din Jabbar pledged allegiance before the New Orleans attack, according to FBI Deputy Assistant Director Christopher Raia -- has been promoting the use of vehicles as a terrorism weapon since around 2014. Sources told ABC News that ISIS has ramped up calls for its supporters to launch low-tech, mass casualty ramming attacks in recent months, especially since the most recent Israel-Hamas conflict began in October 2023.

Jack Brook/AP MORE: FBI releases timeline of suspect Shamsud-Dim Jabbar's New Orleans attack "Law enforcement should be aware that in many cases attackers have conducted vehicle-ramming attacks with secondary weapons and may continue the attack with edged weapons, firearms, or IEDs after the vehicle has stopped," the bulletin said. The tactic could be "attractive" for foreign terrorist organizations and other actors due to its low complexity threshold, the warning said. The bulletin offered law enforcement agencies tips on danger signs of upcoming attacks to look out for, including the use of pre-operational surveillance, fraudulent identity documents or credit to rent vehicles, online calls for violence or unusually placed items which could conceal a improvised explosive devices. The bulletin stated that Jabbar was inspired by ISIS but that there remains no evidence of any co-conspirators. A senior law-enforcement official told ABC News that there is so far no sign of ISIS claiming responsibility for the New Orleans attack. An intelligence bulletin from the New York Police Department obtained by ABC News indicated that ISIS supporters did celebrate the attack online. Violent extremists, the bulletin said, "continue to view densely populated walkways, parades, mass gatherings and other outdoor events along streets, especially during holidays, as vulnerable targets of opportunity." "This enduring threat underscores the criticality of pre-staged blocker cars and the deployment of other effectively configured countermeasures including heavy block, barriers and bollards," it added. The ongoing investigation into the New Year's Day attack on Bourbon Street saw bomb-making materials recovered by FBI agents and local law enforcement at a residence linked to the suspect in Houston, Texas, on Thursday, sources confirmed to ABC News. The items found were also referred to as "precursor chemicals" by agents in the field, sources said. They were discovered during the execution of a search warrant at Jabbar's last known residence in the small community of Greenspoint, in north Houston. Authorities no longer believe there are any other suspects involved in the New Year's truck attack that killed 14 people and injured 35 others, the FBI said Thursday. Sixteen people remain hospitalized at University Medical Center New Orleans, including eight in intensive care. The death toll is not expected to rise beyond 14 people, Dr. Jeffrey Elder of the University Medical Center New Orleans told ABC News Live on Thursday.

Location of New Orleans truck ramming attack Map tiles by Google Earth MORE: Music brings New Orleans' French Quarter back to life After investigators reviewed all surveillance videos, it appears that Jabbar -- a 42-year-old Army veteran and U.S.-born citizen from Texas, who also died in the attack -- placed explosive devices in the area himself and then changed clothes, multiple law enforcement sources told ABC News. The FBI is still investigating whether there were individuals Jabbar spoke to or exchanged messages with prior to the early morning Wednesday attack, but no one was in the vicinity to help him do anything, the sources said. "Federal law enforcement and the intelligence community are actively investigating any foreign or domestic contacts in connection that could possibly be relevant to the attack," President Joe Biden said Thursday. The FBI's Raia called the attack a premeditated "act of terrorism" but said there was no additional threat to the public. The FBI released new surveillance images of Jabbar in New Orleans a little more than an hour before the attack took place, showing the suspect walking along Dauphine Street near Governor Nicholls Street shortly after 2 a.m., wearing a light brown long coat, jeans and brown dress shoes. The FBI also released a photo of one of the coolers containing an explosive device that authorities said Jabbar placed near the intersection of Bourbon and Orleans Street. Surveillance footage showed Jabbar placing two improvised explosive devices in coolers in the Bourbon Street area, Raia said. He had a remote detonator in the truck to set off the two devices, Biden said. "Those are the only two devices that we've been able to recover that were functional -- both devices were rendered safe on scene," he said. Jabbar drove from Houston to New Orleans on Tuesday evening and posted several videos online "proclaiming his support for ISIS," and mentioning he joined ISIS before this summer, Raia said. Jabbar was "hell-bent" on killing as many people as possible, driving a pickup truck onto the sidewalk around a parked police car serving as a barricade to plow into pedestrians, officials said.

Jabbar then exited the damaged vehicle armed with an assault rifle and opened fire on police officers, law enforcement said. He was also armed with a handgun, sources told ABC News. Officers returned fire, killing Jabbar. At least two officers were injured, one by gunfire and the other when the officer was pinned by the truck, authorities said. New Orleans Police Superintendent Anne Kirkpatrick said security bollards were not working at the time because they were in the process of being replaced for next month's Super Bowl. Law enforcement cleared and reopened Bourbon Street on Thursday as the investigation continued. New Orleans Mayor LaToya Cantrell said authorities had the "confidence" to reopen the area to the public ahead of the Sugar Bowl Thursday afternoon, which was initially scheduled for Wednesday but postponed in the wake of the attack. "I want to reassure the public that the city of New Orleans is not only ready for game day today, but we're ready to continue to host large-scale events in our city," she said. "Our hearts and prayers continue to go out to the victims' families," Cantrell added. Louisiana Gov. Jeff Landry on Thursday compared the ongoing investigation to a jigsaw puzzle. 3:10 Biden: No evidence of link between New Orleans attack, Vegas Cybertruck explosionPresident Joe Biden gave an update from the White House following a meeting with members of...Show More The FBI and Department of Homeland Security on Thursday issued a joint intelligence bulletin warning the nation's 18,000 law-enforcement agencies about potential copycats seeking to emulate this week's devastating ramming and shooting attack in New Orleans, ABC News has learned.
