Overview
- A federal alert reviewed by multiple outlets says preliminary signals analysis points to a transmission likely of Iranian origin relayed across several countries shortly after Ayatollah Ali Khamenei was killed on February 28.
- Officials describe the broadcast as encrypted and apparently intended for clandestine recipients with the key, consistent with instructions to covert operatives or sleeper assets.
- Agencies were told to increase monitoring of suspicious radio‑frequency activity, noting the sudden appearance of a station with international rebroadcast characteristics.
- Authorities report no specific, credible threat tied to any location, and the contents of the intercepted message have not been decoded.
- U.S. counterterrorism posture has been elevated, with the FBI and partner agencies intensifying coordination as Iran installs Mojtaba Khamenei and regional hostilities continue.
