Officials from the Department of Homeland Security have announced an immediate increase in security measures at Immigration and Customs Enforcement (ICE) facilities nationwide following a shooting at an ICE office in Dallas on Wednesday.

A gunman fatally shot one migrant detainee and critically injured two others in what DHS Assistant Secretary Tricia McLaughlin described as an incident “driven by hatred for ICE.”

According to McLaughlin, the Texas event marks the latest in a series of “unprecedented violent acts against ICE law enforcement,” which have involved bomb threats, physical assaults, and the online exposure of officers and their families’ private information.

“Our ICE officers are experiencing a more than 1,000% rise in assaults against them,” McLaughlin stated in an official message. “For months, we have urged politicians and the media to reduce their critical rhetoric towards ICE law enforcement to prevent tragic incidents like this.”

The role of ICE officers under the Trump administration in enforcing immigration laws and deporting undocumented individuals has sparked debate. Critics argue that raids often affect migrants who otherwise follow the law. The White House asserts its focus remains on deporting those involved in serious or violent crimes, labeling them as “the worst of the worst.”

In June, President Donald Trump deployed the National Guard to Los Angeles after protests against ICE raids escalated into violence in the predominantly Hispanic city. The President has also criticized sanctuary cities like Los Angeles and Chicago for their lack of cooperation with federal immigration officials.

In the Dallas attack Wednesday, police believe the shooter opened fire from a nearby building around 6:40 a.m. Rounds found near the suspected shooter had messages that were “anti-ICE in nature,” said Joseph Rothrock, FBI special agent in charge of the Dallas Field Office.

No law enforcement personnel were injured. The suspect died by suicide, officials said.
