LOS ANGELES.–Investigated since the opening of the U.S. Cuban embassy in Havana in 2015, Bulgarian investigative journalist Christo Grosev gets closer to fingering an elite Russian agency 29155 as the culprit behind high-frequency acoustic microwave energy attacks that have sickened U.S. government personnel around the planet. When it first happened to U.S. diplomatic personnel in Havana, Cuba it was dismissed as psychosomatic illness, something akin to illusory physical illness associated with post-traumatic stress disorder and other psychological conditions. But on closer inspection of brain-related symptoms, including headaches, memory losses, vertigo, disorientation and nose bleeds, all associated with events in housing related to Commerce and State Department assignment in Cuba, Gauangzhou, China, Shanghai and Tbilisi, each describing a recognizable pattern of hearing strange sounds, before bizarre neurological symptoms developed.
Interviewed State Department security officer Mark Lenzi, CBS “60 Minutes” producers Zill de Granados and Rey said Lenzi reported hearing strange sounds before developing neurological symptoms. Lenzi said he heard a “marble circling down a metal tunnel,” a bizzare out-of-place sound before he and his wife developed neurological symptoms. “This was a directed standoff attack against my apartment. It was a weapon,” Lenzi told “60 Minutes” host Scott Pelley. “I believe it’s RF, radio frequency energy in the microwave range,” Lenzi said. Corroborating evidence showed up at the Eisenhower office building in Washington, D.C. where Olivia Trove, a former Homeland Security counterterrorism official working for Vice President Mike Pence, was hit with a microwave weapon. Trove reported getting so sick she thought she’d down a flight of stairs.
Getting hit at the Eisenhower building was far removed from the U.S. embassy in Havana, Cubia, knowing it was in Washington, D.C. “It was like this piercing feeling on the side of my head . . . and I got like vertigo. I was unsteady. I felt nauseous. I was somewhat disoriented,” Trove told Pelley in 2018. “I remember thinking, like OK . . . don’t fall down the stairs. You’ve got to find your ground again and steady yourself,” attesting to the significant brain effects from whatever microwave energy penetrated her apartment. Deputy chief of staff for Homeland Security Miles Taylor reported said he woke up to a strange sound. He looked out his window and saw a white van pull away from the curb. “I went to the window, opened my window, looked down at the street . . . I see a white van, and the van’s brake light turned on. And it pulled off and sped away.,” said Taylor.
Numerous reports in Washington and around the globe show that the strange neurological symptoms follow bizarre sounds all point to the used by a foreign government of a microwave, radio frequency weapon targets U.S. diplomatic personnel at various locations around the globe. Whatever the original set up in Havana in 2015, it now shows itself moving from government office to hotels or apartments used by U.S. government officials, suggesting that the RF microwave units were mobile in nature. James Benford, a physicist and microwave authority, said portable microwave weapons exist that could damage brain tissue.” “There are many kinds and they can go anywhere in size, from a suitcase all the way up to a large tractor-trailer. And the bigger the device, the longer the range,” Benford said. Zell de Granados said the “smoking gun” hasn’t be found yet.
Benford confirmed that the microwave weapons can penetrate any construction material, leaving everyone vulnerable to targeted attacks. “Practically everything” can be penetrated by the RF weapons said Benford, including walls, glass, and brick,” leaving everything accessible to microwave attacks. Bulgarian investigative journalist Christo Grozev said he uncovered Top Secret Russian intelligence unit 29155, the same unit responsible for poisoning Russian double-agent Sergei Scripal and his daughter Yulia in 2018, then poisoning the late Russian dissident Alexi Navalny in 2021. Grozev said he has a document that links Russian intel Unit 29155 to an acoustic energy weapons, saying services for “potential capabilities of non-lethal acoustic weapons,” coming as close to a smoking gun as it gets. Tracking down microwave attacks to Unit 29155 is a breakthrough in fingering Russia.
When you consider the first 2015 reports of microwave attacks happened in Cuba, it certainly suggests a link to events a CIA-backed Kiev coup in 2015, toppling the Kremlin-backed government of Viktor Yanukovych. Since then, U.S.-Russian diplomatic relations have deteriorated to the point of active warfare in Ukraine against the Kremlin, Russian microwave attacks of U.S. diplomatic personnel around the globe have increased. “We believe members of the Unit 29155 were there in order to facilitate, supervise, or maybe even personally implement attacks on American diplomats, on American officials, using an acoustic weapon,” Grozev told Scott Pelley. U.S. Director of National Intelligence Avril Haines denies the use of microwave weapons on U.S. personnel. “Very unlikely as foreign adversary is responsible,” the same thing she said about China creating the deadly novel coronavirus.
