A militant anti-government activist ignited a gasoline fire outside a Manhattan federal building housing an immigration court Monday, marking the latest violent attack on federal facilities amid escalating tensions over immigration enforcement.

Attack on Federal Plaza

The suspect poured gasoline on the entrance stairs of 26 Federal Plaza before using fireworks to ignite a massive blaze, according to the Department of Homeland Security. Federal Protective Service officers tackled the attacker, who carried two pellet guns, an incendiary device, and a sign declaring “ICE Off Our Streets.” The suspect also possessed what authorities described as a manifesto outlining anti-Immigration and Customs Enforcement ideology. One officer and a civilian sustained minor injuries during the confrontation but were treated and released from medical care.

FBI Assistant Director James Barnacle characterized the incident as an “anti-government attack on a federal facility,” confirming the FBI New York Joint Terrorism Task Force has assumed control of the investigation. The Department of Homeland Security identified the perpetrator as an individual with documented history of anti-ICE activism, labeling him an “anti-ICE rioter” in official statements. Federal authorities have not yet released the suspect’s name or disclosed potential charges, though the severity of attacking a federal building typically carries significant prison time under federal law.

Mayor Responds to Violence

New York City Mayor Zohran Mamdani condemned the attack as “deeply disturbing” while expressing relief that no serious injuries occurred. Writing on social media, Mamdani pledged his administration would “continue to ensure that every New Yorker is safe in their city” and promised to “hold accountable any who threaten that.” The mayor’s statement emphasized public safety concerns arising from politically motivated violence targeting government facilities. Federal Plaza houses multiple government agencies beyond immigration courts, making it a high-traffic location for federal employees and civilians seeking government services throughout the business day.

Pattern of Escalation

The attack represents an alarming escalation in tactics employed by anti-ICE activists, moving beyond protests and demonstrations to direct violence against federal property. While immigration enforcement has sparked heated debate across the political spectrum, the weaponization of incendiary devices crosses constitutional boundaries protecting peaceful protest. The suspect’s preparation—including gasoline, fireworks, weapons, and written materials—suggests premeditation rather than spontaneous action. Federal investigators will likely examine whether the attacker acted alone or coordinated with broader anti-government networks. The incident raises serious questions about security protocols at federal facilities and the potential for copycat attacks by extremists opposed to immigration enforcement.
