According to a report from ABC News, an urgent federal alert was sent across several law enforcement departments, claiming that the U.S. intelligence intercepted several coded signals of Iranian origin, believed to be “an operational trigger” for “sleeper assets” outside the nation.

The alert, which was reviewed by the publication, suggested that the transmission was allegedly broadcast across multiple countries, right after the death of Iran’s Supreme Leader Ayatollah Ali Khamenei in the US-Israel joint strikes.

​The alert claimed that the transmission was allegedly meant only for “clandestine recipients” and may have been meant to send messages to “covert operatives or sleeper assets.”

​Explaining the situation, the alert reportedly said, “While the exact contents of these signals cannot currently be determined, the sudden appearance of a new station with international rebroadcast characteristics warrants heightened situational awareness.”

While the alert also mentioned that there was “no operational threat tied to a specific location,” it reportedly ordered law enforcement agencies to amp up monitoring.

On Monday, March 9, Trump was quizzed about the same incident by the press. In response, Trump said, “They’ve been trying for a long time, and we’ve been very much on top of it.”

“We’re watching every single one of them, yeah. We know a lot about them,” he added.  The president also did not forget to blame the Democrats, claiming tools used to decode these signals from Iran have been stalled because of the ongoing partial government shutdown.

He said, “We’ve got very, very good intelligence on that. Yeah, we know a lot about them. The biggest problem we have is the Democrat shutdown. We know a lot about them, but the shutdown doesn’t allow us to do what we have to do.”

​Before Trump’s statement, former Federal Bureau of Investigation (FBI) Director Chris Swecker raised the alarm. He warned that a Hezbollah or Hamas cell attack on American soil was possible.

Explaining what could happen ahead, Swecker had mentioned, “If ever there’s going to be a Hezbollah cell or a Hamas cell act in the United States in a violent way, it’s now. We know that they have cells here. We also know that there are lone supporters, many of whom have come out in these protest groups.”
