In the wake of Iranian Supreme Leader Ayatollah Ali Khamenei's assassination on February 28, 2026, U.S. federal counterterrorism authorities have raised alarms about possible retaliatory actions from Iran, including sleeper cells, lone wolf attacks, and cyberattacks on American soil. A cryptic shortwave radio transmission, believed to be of Iranian origin, has been detected, which may serve as an operational trigger for sleeper agents. While no specific credible threats have been confirmed, local law enforcement has been advised to remain vigilant.
