The FBI’s warning comes amid escalating US-Iran tensions and a broader uptick in terrorism threats nationwide. On March 13, 2026, federal officials reported increased threats, including an incident in New York City where two men inspired by Islamic State brought homemade bombs to a protest. These developments are occurring alongside reductions in FBI and Justice Department resources, raising concerns about the nation’s ability to address emerging threats.
