The US Homeland Security Department issued a terrorism advisory bulletin on Sunday that warned that the Iran conflict is creating a "heightened threat environment" in America following US strikes on Iranian nuclear facilities.
The agency noted Iran maintains a "long-standing commitment to target US Government officials it views as responsible” for the death of top military commander Qasem Soleimani in January 2020.
The National Terrorism Advisory System bulletin, effective through Sept. 22, warns of likely low-level cyberattacks by pro-Iranian "hacktivists" and potential government-affiliated cyber operations against US networks.
It warned that violent extremist mobilization would likely increase if Iranian leadership issues religious rulings that encourage retaliatory violence against domestic targets.
The bulletin highlighted recent "terrorist attacks" motivated by "anti-Semitic or anti-Israel sentiment," warning that the Israel-Iran conflict could inspire additional US-based plotting.
“The ongoing Israel-Iran conflict brings the possibility of increased threat to the homeland in the form of possible cyberattacks, acts of violence, and antisemitic hate crimes,” said Homeland chief Kristi Noem.
The advisory follows American strikes on three Iranian nuclear sites using bunker-buster bombs at Fordo via B-2 stealth bombers, plus submarine-launched cruise missiles targeting the Natanz and Isfahan facilities.
Joint Chiefs Chairman Air Force Gen. Dan Caine said more than 125 American aircraft participated in the mission, including stealth bombers, fighter jets, refueling tankers, a guided missile submarine and surveillance aircraft.
US President Donald Trump announced that American forces conducted "very successful" strikes on the nuclear sites.
