The US Secretary of State confirmed the media reports that some American diplomats had problems with hearing as a result of work in Cuba.

According to world media reports, in October last year several US diplomats working in Cuba were forced to return to their homeland due to hearing problems. Previously, the same problems arose with a Canadian diplomat.

Tillerson said that Cuba should conduct an investigation into what happened. Speech may go about the possible use of ultrasonic radiators against diplomats. Havana has already rejected all these suspicions, saying that she does not take any action against the diplomats. Diplomatic relations between the United States and Cuba were restored on July 20, 2015. June 16, Trump canceled some of Obama's decrees on the restoration of relations between the two countries.
