According to a report prepared by the Central Intelligence Agency (CIA), the Havana syndrome is not caused by Russia or any other foreign enemy of the United States.
The agency’s finding drew criticism from those who have reported cases and those who accuse the US government of long overplaying the ailments.
This syndrome first became known in 2016 after US diplomats and spies operating in Cuba reported unusual symptoms, including headaches, dizziness, hearing loss and nausea.
At that time it was thought that those affected may have been attacked with some kind of directed energy weapon, although no evidence of this was ever found.
“The notion that the symptoms of widespread brain injury have been caused by Russia or another foreign power targeting Americans around the world, either to harm them or to gather intelligence, has been deemed unfounded,” NBC News reported. citing sources close to the CIA.
From the agency they also point out that most of the cases that the authorities have reviewed would be related to other known medical conditions or environmental factors.
In fact, medical tests have revealed undiagnosed brain tumors or bacterial infections.
However, the agency acknowledged that many other cases still need to be investigated.
“While we have come to some significant interim findings, we are not done yet. We will continue our mission to investigate these incidents and provide access to world-class care for those who need it,” CIA Director William Burns said in a statement.
