A doctor who evaluated American and Canadian diplomats working in Cuba diagnosed them with conditions as serious as mild traumatic brain injury and damage to the central nervous system, CBS News said on Wednesday, citing medical records it reviewed.
The diplomats had complained of symptoms including hearing loss, nausea, headaches and balance disorders after what were described as "incidents" that began affecting them in Havana beginning in late 2016, CBS News said.
Officials are investigating whether the diplomats were targets of some form of sonic attack directed at their homes, CBS reported, citing a source familiar with the incidents. The source said the incidents had continued to occur on the communist-ruled island and that some U.S. diplomats had cut short their assignments there.
