The Department of Homeland Security (DHS) warned about potential terrorist sleeper cells activating in the United States following the U.S. attack against Iranian nuclear facilities.

The National Terrorism Advisory System released a bulletin on Sunday, warning Americans to stay vigilant as the “ongoing Iran conflict is causing a heightened threat environment in the United States.”

The bulletin stated that pro-Iranian hackers are “likely” to target U.S. networks, while also showing concern for Iranian leadership potentially issuing a religious ruling calling for violence in the United States.

“The likelihood of violent extremists in the Homeland independently mobilizing to violence in response to the conflict would likely increase if Iranian leadership issued a religious ruling calling for retaliatory violence against targets in the Homeland. Multiple recent Homeland terrorist attacks have been motivated by anti-Semitic or anti-Israel sentiment, and the ongoing Israel-Iran conflict could contribute to US-based individuals plotting additional attacks,” the bulletin stated.
