A series of new suspected "Havana Syndrome" cases involving at least six U.S. government personnel has emerged, with individuals reportedly receiving treatment at Walter Reed National Military Medical Center near Washington, D.C. These developments have reignited national security concerns, particularly because the reported incidents occurred on American soil rather than at diplomatic facilities abroad, a significant shift from the pattern of previous occurrences.

Investigative journalist Catherine Herridge reported that these six cases surfaced after the summer months. The individuals are reportedly being treated for confirmed or suspected brain injuries, which federal authorities formally categorize as Anomalous Health Incidents (AHIs). Walter Reed is home to the National Intrepid Center of Excellence, a specialized facility for traumatic brain injuries that has previously provided care for government personnel reporting similar neurological symptoms.
The location of these latest suspected incidents has drawn particular scrutiny. Herridge previously documented more than two dozen suspected directed-energy incidents within the United States, including a cluster reported at a government facility in Northern Virginia. Recent months have also seen at least two senior government personnel, involved in projects related to directed-energy technology, reportedly experience suspicious incidents around the Washington area. One individual reportedly works for the Department of War, and another is employed within the Office of the Director of National Intelligence. This apparent overlap has prompted speculation and questions about whether American personnel could be targeted by an unidentified adversary using sophisticated technology.
However, federal investigators have not yet made an official determination that a directed-energy weapon caused the reported injuries. Furthermore, no government or organization has been publicly identified as responsible for these incidents. Accounts from some suspected victims describe unusual circumstances preceding their symptoms. Herridge noted that several individuals reported observing suspicious vehicles nearby shortly before experiencing sudden shocks, disorientation, or other neurological symptoms. Others reported strange behavior from their pets. "I’ve had people tell me that they’ve been walking their dogs” when the animals suddenly reacted, Herridge said. While these accounts suggest unusual events, they do not definitively establish an attack.
The mystery of Havana Syndrome dates back nearly a decade. It first gained widespread attention in 2016 when American diplomats and intelligence personnel stationed in Cuba began reporting unexplained neurological problems. Similar complaints subsequently emerged among American government personnel and their families in various other countries worldwide. Symptoms have consistently included dizziness, ringing in the ears, vertigo, blurred vision, and other neurological disturbances. Some affected individuals also described hearing unusual sounds or experiencing sudden, intense physical sensations immediately before the onset of their symptoms.
These incidents triggered years of extensive investigation into potential causes, including deliberate attacks, environmental factors, unrelated medical conditions, or a combination of multiple factors. In 2023, a significant American intelligence assessment concluded that a foreign adversary was "very unlikely" to be responsible for the broader collection of reported incidents. This conclusion, however, did not fully resolve the controversy, with some affected personnel and lawmakers continuing to question the thoroughness of individual case examinations.
The debate intensified in 2024 following a joint investigation by The Insider, CBS News’ 60 Minutes, and Der Spiegel. This investigation reported evidence that potentially linked Russian military intelligence personnel to certain suspected incidents, focusing partly on members of Russia’s GRU Unit 29155 and their reported proximity to locations associated with some affected Americans. While this reporting raised additional questions, it did not conclusively establish Russian responsibility for the incidents.
The emergence of these new suspected cases near the nation's capital brings these unresolved questions back into sharp focus. Federal authorities are reportedly examining whether a foreign entity could be connected to these latest incidents, though no definitive attribution has been announced. Congress continues its oversight, with the House Intelligence Committee investigating how federal agencies have handled reports from affected personnel and communicated their findings. Mark Lenzi, a former State Department official, recently disclosed that he testified before the committee regarding alleged microwave attacks and the treatment of individuals who reported symptoms.
Walter Reed National Military Medical Center did not immediately respond to requests for comment regarding the latest patients. For the six individuals reportedly receiving treatment, the immediate priority remains their medical recovery. For federal investigators, the ongoing challenge is to determine if the reported incidents share a common cause and, crucially, whether any involve deliberate hostile activity against U.S. personnel on American soil. Nearly a decade after its initial emergence, the origins and nature of Havana Syndrome remain disputed and largely unresolved.
