Two U.S. Immigration and Customs Enforcement (ICE) detainees were killed and one person injured at a Dallas facility Wednesday morning, local media reported citing police sources.

ABC-affiliate WFAA reported that the suspected shooter was found dead on the roof of a nearby immigration attorney's office. 

U.S. Department of Homeland Security Secretary Kristi Noem said in a post on X that there were multiple injuries and fatalities, adding that the gunman died from a self-inflicted gunshot wound.
