The FBI had warned US state and local law enforcement of threats posed by Iran's government to targets within the US, even as the White House played down the likelihood of an attack, Reuters reported.
The FBI and other federal intelligence agencies said the Iranian government 'poses a persistent threat' to US military and government personnel and facilities, Jewish and Israeli institutions, and Iranian dissidents in the US.
However, the report noted that the FBI and the National Counterterrorism Center had not identified any broad threats to the American public.
Iranian security services have attempted to kidnap and kill Americans in recent years, using methods ranging from firearms to 'stabbings, vehicle rammings, bombings, poisoning, strangling, suffocation, and arson.'
Tehran often relies on operatives with legal access to the US and has monitored social media, livestreams and mapping applications to identify targets and assess vulnerabilities.
Authorities were advised to remain vigilant and share any concerning intelligence with federal agencies.
