More mysterious 'Havana Syndrome' attacks

More of these strange attacks have been reported, this time not in Cuba but near the White House.

When they were first reported in 2017, the U.S. government referred to them as 'targeted attacks' but later started calling them 'health incidents.'

But recently, two U.S. senators said they were definitely attacks. Canadian diplomats accused the Canadian government of withholding information about three new cases of brain injury among Canadian diplomats who served in Cuba, too.

The U.S. puts Russia as the most likely perpetrator.

Last year the National Academy of Science found the weapon to be one that uses 'pulsed microwave energy' to cause brain damage.

The reported symptoms are vague, including memory loss, nausea, headaches, and loss of balance. The U.S. diplomats reported hearing a strange noise, which was recorded and is publicly available to listen to, in the embassy before the symptoms started.
