FBI U.S. troops are heading to the Middle East to remain on high alert in the conflict with Iran as the Trump administration escalates its campaign against the Islamic republic, Fox News has learned.

A senior FBI official told Fox News that the Joint Terrorism Task Force (JTTF) remains on high alert and all resources are at the ready if requested or needed by law enforcement partners.

A memo from the U.S. Department of Homeland Security over the weekend warned of possible cyberattacks and lone-wolf attacks amid U.S. and Israeli military bombardments in Iran. The memo did not mention any specific individual attacks but warned of lower-level cyberattacks and other acts of violence.

On Saturday, FBI Director Kash Patel said he directed counterterrorism and intelligence teams to remain on high alert and mobilize all necessary ancillary security assets.

“Our Joint Task Forces across the country are working 24/7 as always to address and disrupt any potential threats to our homeland,” he wrote on X.

“While the military is responsible for force protection overseas, @FBI We remain at the forefront of stopping domestic attacks and will continue to have our teams working around the clock to protect Americans,” he added.

Early Sunday morning, Ndiaga Diagne, a 53-year-old naturalized U.S. citizen born in Senegal, allegedly opened fire at a bar in Austin, Texas, killing three people and injuring 14 others. Investigators found iran flag and photos of regime leaders.

On Monday, Gen. Dan Kaine, chairman of the Joint Chiefs of Staff, said more U.S. troops would be heading to the Middle East but declined to specify how many.

“I don’t want to get into specifics because that would tip off the enemy,” Kaine told reporters at a Pentagon news conference. “We have more tactical aircraft flowing into the theater, just based on the time it takes for them to get to the theater.”

Kaine said the U.S. mission in Iran is to “deter Iran’s ability to project power beyond its borders.”

Meanwhile, War Secretary Pete Hegseth said the mission is to prevent Tehran from producing nuclear weapons and destroy some of its military capabilities.

U.S. Tomahawk missiles from U.S. Navy ship Kaine said U.S. bombers struck naval forces on Iran’s southern flank, and U.S. bombers also struck Iran’s underground facilities.
