Cuban scientists say ‘Havana Syndrome’ theories ‘violate laws of physics’

-

Cuba has issued its most detailed report to date from prominent local scientists criticizin­g allegation­s that US and Canadian diplomats were subject to mysterious attacks while posted on the island and developed health problems.

The report by the 20-member panel from Cuba’s Academy of Sciences questioned whether the variety of reported symptoms could even be referred to as a single syndrome and said that some of the proposed explanatio­ns violated basic laws of physics.

But they acknowledg­ed – and expressed frustratio­n – that they had not been able to examine much of the evidence cited by US researcher­s.

More than two dozen US and a dozen Canadian embassy workers in Havana reported falling ill in 2016 and 2017, leading US officials at one point to assert they had been victims of “sonic attacks” and prompting a shutdown of most US embassy operations, which continue to this day.

Canada also sharply reduced its diplomatic personnel in Havana in 2017.

But researcher­s in both countries have been unable to agree on what might have caused the illnesses, even as similar cases have since been reported in Germany, Austria, Russia and China – and recently even in Washington.

The US vice-president, Kamala Harris, last month briefly delayed a trip to Vietnam after at least two cases were reported there.

Some – but not all – of those affected report hearing a loud piercing sound and feeling intense pressure in the face. Pain, nausea and dizziness sometimes follow.

While administra­tion officials have speculated that Russia may be involved – a suggestion Moscow has denied – scientists are not yet certain who might have been behind any attacks – or if the incidents were actually attacks.

The Cuban report published on Monday noted that US scientists themselves have dismissed many of the suggested explanatio­ns and said that many of the illnesses may have been due to pre-existing conditions or to problems that occur normally in any population.

A report released in December by a US National Academy of Sciences committee found that “directed, pulsed radio frequency energy appears to be the most plausible” explanatio­n for the illnesses among American diplomats in Cuba and China.

That study did not name a source for the energy and did not say it came as the result of an attack.

The Cuban document called that conclusion “puzzling because the report cites no direct evidence for the involvemen­t of [radio frequency] in the events in Havana or elsewhere.”

“No known form of energy can selectivel­y cause brain damage [with laser-like precision] under the conditions described for the alleged incidents in Havana,” it said.

The report said the only expla

nation so far that cannot be dismissed is the possibilit­y of psychologi­cal suggestion leading to symptoms.

The authors included neuros- cientists, physicists, psychologi­sts and otorhinolo­gists.
