Washington has no evidence in Russia's involvement in "acoustic attacks" in Cuba. This was stated by the representative of the US State Department Hiser Neurt. She clarified that the investigation continues and the cause of the incident in the US Embassy in Havana has not yet been established. Neuert called for caution to the information that the press spreads.
The fact that Russia can be involved in the organization of "acoustic attacks" in American diplomats in Cuba and China previously reported the NBC channel. This conclusion supposedly came American intelligence .
In 2016, 26 employees of American diplomatic agents in Havana and Beijing were injured as a result of unknown exposure. The victims complained about headaches, vision problems and temporary hearing loss. Experts suggest that poor health was caused by the influence of ultrasound waves. The US State Department revoked more than half of the diplomatic mission employees. Cuba authorities deny involvement in the incident.
