The United States has no evidence of Cuba’s involvement in so-called sonic attacks on U.S. diplomats, Cuban Ambassador to Russia Gerardo Penalver Portal said on Monday.

In August 2017, the U.S. State Department said diplomats working at its embassy in Cuba were affected by an incident involving a mysterious audio device.

Media reports at the time said some of the diplomats suffered permanent hearing loss and possible brain injuries due to a sonic weapon; over 20 diplomats were affected, according to the State Department.

The Cuban government has denied any involvement in the incidents.

“Cuba has spoken from the outset of its willingness to cooperate in clarifying the circumstances of these so-called attacks.

But the U.S. government continued to produce accusations without any evidence.

Clearly, they want to manipulate politics, “ he told a press conference.

More recently, U.S. diplomats in China also complained of symptoms similar to those suffered by their colleagues in Cuba.

In June, U.S. Secretary of State Mike Pompeo announced that the State Department established a task force to respond to the mysterious sonic incidents overseas.
