Three injured in shooting at US immigration office

Department of Homeland Security Secretary Kristi Noem said in an X post that there were multiple injuries and fatalities and the shooter died by a self-inflicted gun shot wound.

The shooter was found dead on the roof of a nearby building, local ABC affiliate WFAA reported, citing sources.

"Preliminary information is a possible sniper," ICE acting director Todd Lyons told CNN.

Some media accounts said the victims were in critical condition.

A spokesperson for ICE did not immediately respond to inquiries from Reuters. 

The Dallas Police also did not immediately return calls or emails seeking comment.
