A sniper fired into ICE’s facility in Dallas early Wednesday morning, killing one person and wounding two others before taking his own life, authorities said.

Local media reported that those shot in the attack were migrants.

Homeland Security Secretary Kristi Noem said there were “multiple injuries and fatalities.” She said the shooter died from a self-inflicted gunshot.

“While we don’t know motive yet, we know that our ICE law enforcement is facing unprecedented violence against them. It must stop,” Ms. Noem said.

The Dallas Police Department said the gunman was on a nearby building, firing into the “government building.”

It housed U.S. Immigration and Customs Enforcement’s Enforcement and Removal Operations. That’s the deportation arm of the agency.

ICE ERO has faced rising tensions amid President Trump’s push for “mass deportations.”

The Department of Homeland Security says the agency is on pace to set records, drawing condemnation from Democrats who say the agency is sweeping through immigrant communities, breaking Mr. Trump’s promise of prioritizing those with criminal records.

As passions flare, so has violence.

Homeland Security says ICE officers have seen a 1,000% increase in assaults. Critics question those numbers, saying the department has refused to produce breakdowns.

Still, the number of high-profile incidents is striking. A sitting member of Congress has been charged, as have local politicians in sanctuary cities.

But violence against ICE has long been an issue, dating back to the first Trump administration.

In 2019, someone shot through the window of the agency’s office in San Antonio.

And later that year, a man was shot and killed by authorities while he was trying to ignite propane tanks at an ICE detention facility.

He left a manifesto with anti-ICE rhetoric that echoed the complaints of prominent Democrats at the time, saying he was striking against “the forces of evil” and calling ICE’s migrant detention “concentration camps.”

Anger at the wave of illegal immigrants has also sparked violence. Analysts have tied mass shootings in Buffalo, New York, and El Paso, Texas, in recent years to people angered over a surge of Hispanic migrants they believed were supplanting Americans.
