A detainee has died and two others are critically injured after a rooftop sniper opened fire at an Immigration and Customs Enforcement (ICE) center in Dallas, Texas, officials say. The gunman fired indiscriminately at the ICE facility and at a nearby unmarked van, law enforcement officials say, before dying from a self-inflicted gunshot wound. No law enforcement were injured. FBI Director Kash Patel posted a photo on X of unused ammunition recovered from the scene. One casing has the phrase 'ANTI-ICE' on it. It is the latest in a string of attacks on ICE facilities in recent months as the agency ramps up efforts to deliver on US President Donald Trump's pledge for mass deportations. While the investigation is ongoing, an initial review of the evidence shows an ideological motive behind this attack, Patel wrote on X. These despicable, politically motivated attacks against law enforcement are not a one-off. The Department of Homeland Security (DHS) reported three detainees were shot during the incident. The identified shooter, Joshua Jahn, died from a self-inflicted gunshot, with a previous history of issues related to cannabis. The ongoing investigation is revealing motivations that highlight the complex political climate surrounding immigration enforcement in the United States.}
