Summary

A yearlong investigation by The Insider links Russia’s GRU Unit 29155 to Havana Syndrome attacks on U.S. diplomats and officials worldwide, revealing covert use of directed energy weapons.

The Insider, in collaboration with 60 Minutes and Der Spiegel, conducted a yearlong investigation uncovering evidence that unexplained health incidents known as Havana Syndrome are linked to directed energy attacks by Russia’s GRU Unit 29155. The unit, known for assassinations and sabotage, has been geolocated near victims worldwide, including at least two attacks in Tbilisi, Georgia, in October 2021 and Frankfurt, Germany, in 2014. Victims include U.S. Embassy personnel, their families, and other government employees. The investigation reveals travel logs, call metadata, and eyewitness testimony identifying operatives, including Albert Averyanov, son of the Unit 29155 commander. The unit has a history of high-profile covert operations such as the Skripal and Gebrev poisonings and armament depot bombings in Europe. Health effects from attacks include neurological symptoms and traumatic brain injuries. Despite a 2023 intelligence report deeming foreign involvement “very unlikely,” former U.S. intelligence officials and victims challenge this assessment. The U.S. government has enacted the Havana Act to compensate victims. The report exposes operational details, covert travel, weapon development related to "non-lethal acoustic weapons," and raises questions about intelligence community transparency and accountability.

  "description": "A detailed investigative report by The Insider, 60 Minutes, and Der Spiegel links the Kremlin’s GRU Unit 29155 to the origin of Havana Syndrome attacks affecting more than one hundred U.S. government personnel and their families worldwide. The article documents multiple incidents including a 2021 targeted attack on a U.S. Embassy official's wife in Tbilisi, Georgia, who identified Albert Averyanov—22-year-old son of the unit’s founding commander—as present near her home during the attack. It reveals Unit 29155 as a global assassination and sabotage wing of Russia's military intelligence, responsible also for previous poisonings (Skripal, Gebrev), failed coup attempts (Montenegro 2016), and ammunition depot explosions in Europe. The operatives employ \"non-lethal acoustic weapons\"—sound and radiofrequency directed energy devices believed to cause the neurological symptoms characteristic of Havana Syndrome, including headaches, vertigo, tinnitus, cognitive impairment, and traumatic brain injury. The report outlines covert travel patterns and operational covers, such as using transit through third countries to mask true destinations, and highlights intelligence community fractures, including a disputed 2023 ODNI assessment dismissing Russian culpability. Victims express frustration and feelings of betrayal amid ongoing health issues and skepticism of official conclusions. The article includes first-hand victim testimony, intercepted Russian documents, travel data, and expert commentary from former CIA and DIA officials.",
