Investigative findings into the Havana syndrome reveal fresh intelligence testimonies pointing to Russian energy weapons and high-level government concealment in Washington and London. A major investigation published on Saturday (10) by special correspondent Shaun Walker details new accounts from United States intelligence operatives affected by anomalous health incidents, setting the stage for renewed scrutiny over whether federal agencies suppressed evidence of directed-energy strikes.
The findings preview evidence compiled by investigative journalists and 60 Minutes producers Michael Rey and Oriana Zill de Granados, who release their investigative volume on Tuesday (13). Titled The Havana Syndrome: Secret Weapons, a Government Cover-Up, and the Greatest Spy Mystery of Our Time, the 336-page book published by Crown Publishing Group, an imprint of Penguin Random House, carries a hardcover cover price of US$ 33 in the American market.
Stanford scientist David Relman points to microwave energy and cover-up
David Relman, a professor at Stanford University who led the official United States government scientific panel on the phenomenon in 2022, stated that a distinct subset of cases cannot be explained by known medical or environmental causes. Relman confirmed that his team analyzed medical files and accessed more than 1,000 classified documents during the inquiry, concluding that the injuries are plausibly linked to pulsed microwave energy devices that have been developed for decades in the Soviet Union and Russia.

“To any reasonable person looking at all the evidence I was able to see, it inevitably leads to the conclusion that there may have been a cover-up,” Relman stated. The scientific leader emphasized that while widespread publicity may have spurred false reports among personnel, clinical evaluations showed objective injuries in a core group of affected officers, challenging past dismissals from administrative officials.
Intelligence director Tulsi Gabbard rescinded 2023 government assessments
The debate over official findings escalated following executive action by United States Director of National Intelligence Tulsi Gabbard. On Friday, June 12, 2026, Gabbard issued a formal memorandum rescinding two Biden-era assessments from 2023 that had concluded it was very unlikely that a foreign adversary orchestrated the anomalous health incidents. Gabbard stated that the prior intelligence conclusions suffered from the selective exclusion of evidence and mischaracterization of intelligence sources.
The revoked assessments had previously divided intelligence branches. By the end of the Biden administration, five intelligence agencies maintained that foreign adversary involvement was very unlikely, while one agency determined there was a roughly even chance that an adversary deployed a novel weapon or prototype device against American operatives.
Former CIA officer Marc Polymeropoulos describes Moscow hotel incident
Marc Polymeropoulos, the former deputy chief of operations for Europe and Eurasia at the Central Intelligence Agency, became the first agency official to speak publicly under his own name about his affliction. Polymeropoulos fell severely ill in early December 2017 during a liaison trip to Moscow, where he had traveled to meet counterparts from Russia’s Foreign Intelligence Service and Federal Security Service amid an American drive to counter Russian intelligence activities globally.
“I had vertigo and a splitting headache. I thought it was food poisoning at first, I thought I was going to puke and crap my brains out, and I remember being like, holy shit, the room is spinning and my ears are ringing,” Polymeropoulos stated. Following his departure from the agency in 2019, clinical evaluations at Walter Reed National Military Medical Center diagnosed him with a mild traumatic brain injury, qualifying him in 2023 for financial compensation under the Havana Act, a law passed by the United States Congress in 2021 to assist personnel injured by hostile actions while on assignment.
Operatives report severe attacks across Europe and the Balkans
Unidentified operatives also provided accounts of sudden physical incapacitation while tracking Russian foreign operations. A senior CIA officer whose identity remains classified due to national security reported waking up in an unbearable state of pain in a London hotel room in April 2019, followed by a second episode in Warsaw, Poland, in September 2019. The operative described the sensation as “someone standing over me with a baseball bat and just repeatedly hitting me on the head,” an incident that left him with long-term nerve damage and chronic fatigue.
A researcher from an American defense institute, who requested anonymity, reported experiencing sudden illness in Belgrade, Serbia, in 2015 after suspecting she was being followed through the city. While approaching her hotel room, she experienced severe nausea, sudden gravitational pressure, and a laptop screen flickering with blue static that permanently disabled the machine. Over subsequent weeks, the researcher developed speech impediments and persistent pain that felt like a drill going into her eye, ultimately forcing her to resign from her post.
Ten years of dispute over weapon signatures and mass psychogenic illness
Debate among researchers and medical experts has persisted since mass reports emerged in 2016 among American diplomats stationed in Havana, Cuba, shortly after the restoration of bilateral diplomatic ties under President Barack Obama. Sociologist Robert Bartholomew and neurologist Robert Baloh argued in earlier publications that the phenomenon represented mass psychogenic illness driven by workplace stress, while neuroscientist Douglas Fields asserted that energy weapon claims contradicted physics. Conversely, Georgetown University forensic neuroscientist James Giordano identified distinct clinical signatures across patients, including sudden onset, localized physical pressure, and profound vestibular disruptions.
Historical files indicate that related concerns predate the Cuban cluster. National Security Agency counterintelligence officer Mike Beck, who died in 2026 after developing early-onset Parkinson’s disease, received workplace compensation backed by a declassified 2014 agency document that linked his 1990s assignment in a hostile foreign territory to high-powered microwave systems designed to weaken or disable targets. In late 2014, American consulate workers in Frankfurt, Germany, also experienced sudden symptoms, including an employee found unconscious in a stairwell after hearing high-pitched noise.
The health incidents expanded in 2021, when more than 100 CIA operatives and government officials reported episodes across several countries, including an outbreak in Vienna that disrupted operations and prompted the recall of the local station chief. The upcoming publication of the investigation by Rey and Zill de Granados on October 13, 2026, places the documented accounts and declassified records before the public as federal agencies reconsider their posture on foreign culpability.
