() Bullets fired from a gun used in a fatal shooting at the Dallas Immigration and Customs Enforcement field office contained “anti-ICE” language, the FBI announced on Wednesday.

FBI Director Kash Patel included a photo of the bullet casings found at the scene, one of which had “anti-ICE” written on it.

“These despicable, politically motivated attacks against law enforcement are not a one-off,” Patel wrote in the post on X. “We are only miles from Prarieland Texas, where just two months ago an individual ambushed a separate ICE facility targeting their officers. It has to end and the FBI and our partners will lead the these investigative efforts to see to it that those who target our law enforcement are pursued and brought to the fullest extent of justice.”

Joseph Rothrock, the special agent in charge of the FBI’s Dallas field office, said at a news conference that “anti-ICE” messaging was found on the bullets. He said the FBI is investigating the shooting as an act of targeted violence.

Rothrock said that federal officials will take a “whole of government” approach to investigating the shooting. He confirmed that no members of law enforcement were injured in the shooting.

Texas Sen. Ted Cruz, a Republican, said at the news conference that the shooting was the third in Texas directed at an ICE officer or Customs and Border Protection agent.

“This needs to stop,” Cruz said. “Violence is wrong, politically motivated violence is wrong.”

Cruz pointed his comments at politicians using anti-ICE rhetoric or demonizing ICE and CBP, instructing them to stop.

“This has very real consequences,” he said. “Look, in America, we disagree. That’s fine, that’s the Democratic process. But your political opponents are not Nazis. We need to learn to work together without demonizing each other, without attacking each other.”

Sen. Cory Booker, D-N.J., called the shooting an “unacceptable act of violence” in a social media post.

“My heart is with the victims and their loved ones,” Booker wrote. “While we don’t know all of the details yet, what we can, and all should, agree on is that the vilification of any group of people endangers them. It makes them targets. And it must stop. We are at an inflection point in our history where we must put in the work to break down our divisions and see our shared humanity. We cannot choose the path of hatred and division.
