A federal memo warns law enforcement nationwide about potential lone‑wolf and cyber attacks as tensions with Iran escalate.
The FBI is reported to be on high alert while the Trump administration pursues an intensified military campaign against the Islamic Republic.
U.S. forces have surged into the Middle East after coordinated American and Israeli strikes on Iranian military infrastructure in recent days.
A senior FBI official told Fox News that the Joint Terrorism Task Force remains fully activated across the country.
The official said JTTFs are on high alert and ready to provide resources if requested by law enforcement partners.
Over the weekend the Department of Homeland Security circulated a memo cautioning agencies about lower‑level cyberattacks and individual acts of violence inspired by global events.
The DHS memo did not name any specific plot or individual threat but warned that the bombing campaign against Iran could raise the risk of retaliatory activity on U.S. soil, according to Fox News.
“Our JTTFs throughout the country are working 24/7, as always, to address and disrupt any potential threats to the homeland,” FBI Director Kash Patel wrote on X on Saturday.
“While the military handles force protection overseas, the @FBI remains at the forefront of deterring attacks here at home and will continue to have our team work around the clock to protect Americans,” he added.
Recent Austin Attack and Investigation
The memo arrives days after a deadly mass shooting in downtown Austin that prompted a federal terrorism inquiry.
Gunfire broke out in the early hours of March 1 outside Buford’s Backyard Beer Garden on Sixth Street, one of Austin’s busiest nightlife areas.
Three people, including the shooter, were killed and 14 others were wounded in the incident.
The suspect, identified as 53‑year‑old Ndiaga Diagne, was shot and killed by police after allegedly opening fire from his vehicle and then on foot.
Authorities quickly noted troubling indicators.

Diagne was reportedly wearing a hoodie reading “Property of Allah” over a shirt featuring the modern Iranian flag.
Investigators also recovered a Quran, an Iranian flag, and images of Iranian leaders among his belongings.
The presence of those items prompted the FBI and the Joint Terrorism Task Force to open a full terrorism investigation.
Officials have stressed that no formal ties to a foreign organization have been confirmed and that the suspect may have acted alone.
Investigators continue to examine whether he was directly influenced by recent geopolitical developments.
U.S. and Allied Military Action
Just days before the Austin attack the United States and Israel carried out major strikes on Iranian military targets to degrade Tehran’s missile and military capabilities.
President Donald Trump confirmed the operations were underway and said they were necessary to neutralize threats against American forces and allies.
Defense Secretary Pete Hegseth and Joint Chiefs leadership declared the United States would continue striking Iranian targets “without apology or hesitation.”
Republican leaders in Texas, including Governor Greg Abbott, have framed the Austin shooting in the context of broader national security concerns and the risk of extremist‑inspired violence amid global conflict.
For now federal authorities say there is no confirmed coordinated domestic campaign but the DHS memo makes clear that lone actors inspired by overseas events remain a primary concern.
