FBI Intensifies Vigilance as DHS Memo Cautions Against Potential Lone Wolf Attacks Amid Conflict with Iran

The FBI is maintaining a heightened state of vigilance as tensions escalate between the United States and Iran, with American troops being dispatched to the Middle East. This development follows the Trump administration’s intensified measures against the Islamic Republic, according to information obtained by Fox News.

A senior FBI representative has confirmed that the Joint Terrorism Task Force (JTTF) is on high alert, fully prepared to deploy resources if assistance is requested by law enforcement partners.

Adding to the urgency, a recent memo from the Department of Homeland Security, distributed over the weekend, highlighted the risks of potential cyber threats and lone wolf attacks in light of the ongoing military actions by the U.S. and Israel against Iran. While the memo does not specify any particular attacks, it underscores the possibility of lower-level cyber assaults and other forms of violence.

In response to these tensions, FBI Director Kash Patel has directed counterterrorism and intelligence teams to remain vigilant and has instructed them to mobilize all necessary security assets to support ongoing efforts. This directive emphasizes the importance of readiness in facing any potential threats that may arise during this period of conflict.

“Our JTTFs throughout the country are working 24/7, as always, to address and disrupt any potential threats to the homeland,” he wrote on X. 

“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. 

Early Sunday morning, Ndiaga Diagne, a 53-year-old naturalized U.S. citizen who was born in Senegal, allegedly killed three people in a shooting that left another 14 people injured at a bar in Austin, Texas. At his home, investigators found an Iranian flag and photos of regime leaders.

Police shot and killed the gunman, who used a pistol and a rifle in the shooting.

On Monday, Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said more U.S. troops were headed toward the Middle East, but declined to specify how many.  

“I don’t want to talk specifics, because that would tip the enemy off,” Caine told reporters during a Pentagon briefing. “We have more tactical aviation flowing into theater just based on the time it took to get it out there.”

The U.S. mission in Iran, Caine said, is to “prevent Iran from (the) ability to project power outside its borders.”

Meanwhile, War Secretary Pete Hegseth said the mission is to prevent Tehran from producing a nuclear weapon, as well as destroying some of its military capabilities.

U.S. tomahawk missiles fired from U.S. Navy vessels have struck Iranian naval forces along the southern flank, and American bomber planes have hit underground Iranian facilities, Caine said.
