'Havana syndrome' likely caused by directed microwaves - US report
Mystery illness suffered by US diplomats in Cuba was most likely caused by directed microwave radiation, a US government report has found. The report by the National Academies of Sciences does not attribute blame for the directed energy waves. But it said research into the effects of pulsed radio frequency energy was carried out by the Soviet Union more than 50 years ago. The illnesses first affected people at the US embassy in Havana in 2016-17. Staff and some of their relatives complained of symptoms ranging from dizziness, loss of balance, hearing loss, anxiety and something they described as "cognitive fog". It became known as "Havana syndrome".
