This is a bizarre story about “sonic attacks” on U.S. diplomats in Cuba.
The United States delivered an ominous warning to Americans on Friday to stay away from Cuba and ordered home more than half the U.S. diplomatic corps, acknowledging neither the Cubans nor America’s FBI can figure out who or what is responsible for months of mysterious health ailments…
To medical investigators’ dismay, symptoms have varied widely. In addition to hearing loss and concussions, some people have experienced nausea, headaches and ear-ringing. The Associated Press has reported some now suffer from problems with concentration and common word recall.
Some U.S. diplomats reported hearing loud noises or feeling vibrations when the incidents occurred, but others heard and felt nothing yet reported symptoms later. In some cases, the effects were narrowly confined, with victims able to walk “in” and “out” of blaring noises audible in only certain rooms or parts of rooms, the AP has reported
So the facts are that people are reporting symptoms and bizarre experiences, and nobody has figured out what or who is causing it.
