Inside mysterious ‘beam of energy’ illness striking US citizens linked to Russian intelligence unit

The mysterious "Havana Syndrome" is widely believed to be an attack from Russia thanks to a joint investigation by The Insider, Ser Spiegal and CBS, though Moscow has denied the allegations

An investigation into a mysterious illness that's been affecting US national security officials and their families has been linked to Russia, marking another development in the five-year inquiry.

The illness is called "Havana Syndrome" and can cause dizziness, fatigue, memory loss and impaired vision. A joint investigation by The Insider, Der Spiegal and CBS's 60 Minutes suggested those afflicted with the illness fell victim to Russian sonic weaponry. Those who believe they have experienced the strange illness opened up during the show about their experiences.

However, Moscow has scoffed at the allegations and US officials said it's unlikely that a foreign power is afflicting US citizens. Those findings were reported last year, so people suffering from "anomalous health incidents" (AHI) have been eagerly awaiting another explanation—a lack thereof has led to frustration.

Additionally, there is a split among the different intelligence agencies involved as they each have varying levels of trust in the inquiry, according to American officials. Scott Pelley and his team of producers, who have been conducting the investigation, appeared on 60 Minutes this week to speak about their findings.

They reportedly found a link between attacks in Tbilisi, Georgia and a top-secret Russian intelligence unit, asserting that the aforementioned Russian group conducted acoustic weapon testing. A source claimed the producers were able to acquire "a receipt."

Lt. Col. Greg Edgreen, a retired Army lieutenant colonel who spearheaded the Pentagon investigations into AHIs, said he wholeheartedly believes Russia is behind the illnesses, claiming its a part of an over-arching scheme to neutralise US personnel. He said: "If my mother had seen what I saw, she would say, 'It's the Russians, stupid'."
