Iran may be activating sleeper cells, alert says
The encrypted Iranian signal may activate sleeper cells amid heightened global tensions, prompting arrests in the UK and Qatar, with authorities urging increased vigilance.
- On March 9, 2026, U.S. agencies intercepted an encoded transmission likely of Iranian origin that may serve as an 'operational trigger', prompting a federal alert to U.S. law enforcement agencies.
- The intercept was relayed across multiple countries shortly after the reported death of Iran's former Supreme Leader Ayatollah Ali Khamenei, with authorities warning covert operatives can receive instructions via encoded radio-frequency broadcasts without internet.
- Detectives from Counter Terrorism Policing London were granted more time to question four arrested suspects, who can be held until March 13, while an SAS deployment to London remains unconfirmed by the Ministry of Defence.
- The advisory told agencies to heighten monitoring of suspicious radio‑frequency activity while no specific target was identified, raising concern among U.S. and allied security services as the FBI declined to comment.
- Security analysts warn a worst-case scenario could mirror 2017's five incidents that killed 40 and injured more than 900; last week Qatar announced arrest of 10 suspects linked to the Revolutionary Guard Corps.
