Austin mass shooting at Buford’s: FBI finds terrorism indicators on gunman Ndiaga Diagne one day after U.S.-Israel Iran strike

Two people are dead, 14 hospitalized, and a federal terrorism investigation is underway after a gunman opened fire on patrons outside Buford’s Backyard Beer Garden on Austin’s West Sixth Street in the early hours of Sunday, March 1, 2026.

The Federal Bureau of Investigation confirmed it is examining a “potential nexus to terrorism” in connection with the attack, which unfolded just before 2 a.m. local time in the heart of Austin’s entertainment district. The suspected gunman, identified by multiple federal law enforcement officials as 53-year-old Ndiaga Diagne, a naturalized U.S. citizen originally from Senegal, was shot and killed by Austin Police Department officers within minutes of the attack beginning. Three people, including Diagne, were pronounced dead at the scene. Of the 14 transported to local hospitals, three remained in critical condition as of Sunday afternoon.

Austin Police Chief Lisa Davis said Diagne drove a large SUV around the block near Buford’s several times before activating his hazard lights, rolling down his window, and opening fire with a pistol on customers seated on the bar’s outdoor patio and standing in front of the entrance. He then drove westbound on Sixth Street, parked the vehicle near Wood Street, exited on foot carrying a rifle, and continued shooting at pedestrians in the area. Officers who were pre-deployed to the entertainment district during peak weekend hours confronted Diagne as he walked eastbound toward Sixth Street and fatally shot him at an intersection. A pistol and a rifle were recovered at the scene. Diagne never entered Buford’s; all fire from his position came from outside the building.

Alex Doran, acting special agent in charge of the FBI’s San Antonio field office, told reporters at a Sunday morning news conference that investigators had identified indicators pointing toward a terrorism connection. “There were indicators on the subject and in his vehicle that indicate potential nexus to terrorism,” Doran said. “Again, it’s still too early to make a determination on that. That’s why we are investigating it very closely with our partners with the Austin Police Department.” The FBI’s Joint Terrorism Task Force, which includes agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives and Texas state police, assumed lead investigative responsibility. Doran declined to specify whether the inquiry was oriented toward domestic or international terrorism.

The terrorism indicators disclosed publicly are significant. Law enforcement sources told multiple news organizations, including CBS News and the Associated Press, that Diagne was wearing a sweatshirt reading “Property of Allah” at the time of the attack and an undershirt bearing an Iranian flag design. A Quran was found in his vehicle. When federal agents executed a search warrant at Diagne’s residence in Pflugerville, a suburb north of Austin, they found an Iranian flag and photographs of Iranian leaders inside the home. Investigators said they are examining whether Diagne self-radicalized and whether his actions were connected to international extremist ideology, while also noting that he had a documented history of prior mental health episodes in Austin.

What do we know about Ndiaga Diagne, the suspect in the Austin 6th Street shooting?

According to the Department of Homeland Security, Diagne entered the United States on March 13, 2000, on a B-2 tourist visa. He became a lawful permanent resident in June 2006 through an IR-6 visa based on marriage to a U.S. citizen and was naturalized as an American citizen on April 5, 2013. He subsequently applied for asylum in 2016. DHS records show a 2022 arrest in Texas for a vehicle collision with property damage. Sources cited by the New York Post and Newsweek noted a prior arrest history in New York City, including an unauthorized vending citation in 2001.

Diagne lived in Pflugerville at the time of the shooting. His ex-wife, reached by ABC News via telephone, confirmed the two divorced in 2022 and that she had not spoken to him in four to five years. She said she was shocked to learn of the attack and described him as religious. Investigators believe Diagne acted alone and that the incident represents an isolated event rather than a coordinated operation.

Is there a link between the Austin shooting and the U.S.-Israel strike on Iran that killed Ayatollah Khamenei?

The shooting occurred one day after the United States and Israel conducted a major military strike on Iran that resulted in the death of Supreme Leader Ayatollah Ali Khamenei. Texas Governor Greg Abbott explicitly referenced the Middle East conflict in a Sunday statement, though FBI officials at the news conference did not confirm any direct connection between the attack and those events. Abbott, who had already directed increased security at sensitive state infrastructure locations in response to the Iran strikes, announced that the Texas Department of Public Safety would expand weekend patrols along Sixth Street.

“To anyone who thinks about using the current conflict in the Middle East to threaten Texans or our critical infrastructure, understand this clearly: Texas will respond with decisive and overwhelming force to protect our state,” Abbott said. U.S. Senator Ted Cruz, appearing on CBS News’s Face the Nation with Margaret Brennan on Sunday, said it was too early to confirm a terrorism connection. “At this point, we don’t know what the evidence will show in terms of whether this was an act of terrorism,” Cruz said. The National Counterterrorism Center, an office under the Director of National Intelligence, confirmed it had deployed representatives to Austin to work alongside the FBI and local law enforcement on the investigation. White House Press Secretary Karoline Leavitt confirmed that President Donald Trump had been briefed on the shooting.

The geopolitical timing is notable. Mass casualty attacks following major U.S. military operations have historically raised concerns about retaliatory or inspired violence by individuals with sympathies toward adversarial governments or ideological movements. Whether Diagne had any contact with foreign networks, accessed extremist online content, or acted independently of any external influence remains the central question facing investigators. Sources familiar with the preliminary inquiry told NBC News that Diagne appeared to be a lone actor with no confirmed state ties, though those assessments are explicitly preliminary.

How did Austin police and emergency services respond so quickly to the West Sixth Street shooting?

The speed of the emergency response was cited by Austin Mayor Kirk Watson and other officials as a decisive factor in limiting casualties. Austin-Travis County EMS Chief Robert Luckritz said the agency received an initial call at 1:39 a.m. and had the first paramedics and officers on scene treating patients within 57 seconds. That response time was enabled by a standing program that embeds paramedics with Austin Police Department teams during peak entertainment district hours on weekends. More than 20 EMS resources responded in total. All patients in critical condition were removed from the scene within 24 minutes of the first call. All remaining patients were transported within 47 minutes.

“There is no question in my mind that the quick response of the police officers and of our EMS personnel and those professionals made a difference and saved lives,” Mayor Watson said. At least four of the 14 hospitalized patients had been discharged from local hospitals as of Sunday evening, according to St. David’s Medical Center.

Kelson Li, who was at Buford’s that night, told local outlet KUT that he heard roughly six gunshots as he walked back toward the bar from a nearby venue. Inside, he found seven or eight people on the ground with bystanders performing CPR. Police arrived approximately 30 seconds after he did. “These are just people trying to let loose, have fun,” Li said. “It’s just pretty surreal to see that it can just go away in a second.”

What does the FBI’s Joint Terrorism Task Force investigation mean for the Austin shooting case going forward?

The JTTF’s formal involvement signals that this investigation has moved beyond a standard homicide inquiry. The task force operates at the intersection of local law enforcement and federal counterterrorism infrastructure, and its engagement typically means investigators are probing digital footprints, communications networks, financial activity, and potential foreign contacts. Retired FBI supervisory special agent Jason Pack told Fox News that agents would likely trace Diagne’s digital history, including social media accounts and device contents, to map any radicalization pathway or contact with extremist networks. ATF agents are separately tracing the pistol and rifle used in the attack to establish how and when Diagne acquired them. Associates, family members, neighbors, and former colleagues will be interviewed as part of building a behavioral baseline and identifying any potential warning signs that were missed.

The FBI’s Doran confirmed that evidence response personnel and digital forensics teams were deployed to the scene Sunday morning. Investigators are working in lockstep with APD, Doran said, and the process of fully determining motive will take time. The Austin Police Department has asked members of the public with information related to the shooting to contact APD victim services at 512-974-5037 or submit tips through Capital Area Crime Stoppers at 512-472-8477.

Buford’s Backyard Beer Garden sits at the intersection of West Sixth Street and Rio Grande Street in a dense block that includes several other bars and nightlife establishments near the University of Texas campus. As of Sunday evening, West Sixth Street from Wood Street to Nueces Street and Rio Grande Street from Fifth Street to Seventh Street remained closed to all traffic as the investigation continued.
