Core Event: Intercepted Communications and Radio Signals
The U.S. government has issued an alert indicating that Iran may be activating sleeper cells outside its borders, following the interception of encrypted communications believed to originate from Iran. This alert, reviewed by ABC News, suggests that these transmissions could serve as operational triggers for covert operatives or sleeper assets, particularly in the wake of the U.S.-Israeli attack that resulted in the death of Ayatollah Ali Khamenei on February 28, 2026. The alert emphasizes the need for heightened situational awareness among law enforcement agencies, although it notes that there is currently no specific operational threat linked to a particular location.
Background & Context: The Emergence of Mysterious Broadcasts
Shortly after the onset of hostilities in Iran, reports emerged of mysterious radio broadcasts in Persian on a shortwave frequency. These broadcasts, which began approximately 12 hours after the U.S.-Israeli bombardment, feature a male voice reciting numbers followed by the word "tavajjoh," meaning "attention." This method of communication, often referred to as a "numbers station," is historically associated with intelligence agencies and is thought to be a means for Iran to communicate with its overseas agents.
The Nature of the Broadcasts
The shortwave radio signals are particularly effective for long-distance communication, as they can travel vast distances by bouncing off the Earth's atmosphere. This method is less traceable than digital communications, which have been compromised in the past. The broadcasts are speculated to be intended for Iran's sleeper cells, allowing for covert instructions without reliance on internet or cellular networks. However, there are conflicting theories regarding the origin and purpose of these broadcasts, with some suggesting they may be aimed at the Iranian opposition.
Criticism & Opposition: Diverging Theories on Broadcast Intent
While some experts assert that the broadcasts are intended for Iranian sleeper cells, others argue that the Iranian government has attempted to jam the signals, indicating that the broadcasts may instead be targeting opposition groups. Triangulation data has suggested that the signals could be emanating from locations near the Red Sea, raising the possibility that foreign intelligence agencies, such as the CIA or Mossad, may be involved in the broadcasts. One expert noted, "The station broadcasts encrypted messages in Farsi twice a day... Messages are separated by the word Tavajjoh."
Conflicting Reports & Gaps: Uncertainty Surrounding the Source
There is significant speculation regarding the true source of the broadcasts. Some listeners have identified similarities between the signals and those of known Russian stations, leading to theories that Russia may be behind the broadcasts. However, the lack of definitive evidence leaves the true origin and intent of the broadcasts open to interpretation.
What's Next: Monitoring and Response
In light of these developments, U.S. law enforcement agencies are being instructed to increase their monitoring of suspicious radio-frequency activity. The situation remains fluid, with ongoing assessments of the potential implications of these communications for both national and international security.
