A detainee has died and two others are critically injured after a rooftop sniper opened fire at an Immigration and Customs Enforcement (ICE) centre 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, he added.


Dallas police responded to an assistance call at the facility around 06:40 local time (11:40 GMT). The Department of Homeland Security (DHS) confirmed that among the injured detainees was a Mexican national.


The shooter has been identified as 29-year-old Joshua Jahn, who died of a self-inflicted gunshot wound. Authorities revealed that he had been registered as an independent voter in 2024 and had previous cannabis-related charges dating back to 2016.


FBI special agent Joe Rothrock stated that the rounds found near the gunman contained messages that are anti-ICE in nature. This incident marked another attack on ICE, a trend that has seen an increase in politically motivated violence during politically charged times.


Texas Senator Ted Cruz condemned these acts of violence, emphasizing that political differences should not lead to demonization and violent actions. Governor Greg Abbott asserted that the incident would not hinder the ongoing efforts in immigration enforcement.


In light of the increasing targeted violence against ICE facilities, officials are calling for a more civil discourse to mitigate the risks associated with inflammatory political rhetoric.
