Study reveals “sonic weapon” used in Cuba against US diplomats may have been pesticide


A new study commissioned by the Canadian government revealed that the mysterious buzzing sound associated with the so-called “sonic attacks” on dozens of Canadian and US diplomats living in Cuba may have been caused by a pesticide.

During a Thursday interview with CBC News, the lead author of the clinical study commissioned by Global Affairs Canada, Alon Friedman, said that his team of researchers found that two agents commonly found in fumigation products were the elements that affected the diplomats.

Friedman explained that Embassy records showed that offices and the inside and outside of the diplomatic residences in Havana were sprayed five times more frequently by the Cuban regime. He then pointed out that toxicology reports of the diplomats confirmed the presence of organophosphate and pyrethroid.

“There are very specific types of toxins that affect these kinds of nervous systems…and these are insecticides, pesticides, organophosphates—- specific neurotoxins,” Friedman told CBC News.

“We will continue the research in other ways to try to confirm which of the toxins is more toxic, at what levels – many things are not known yet,” he added.
