At least one Canadian diplomat in Cuba has been treated for hearing loss following disclosures that a group of American diplomats in Havana suffered severe hearing loss that US officials believe was caused by an advanced sonic device.
In the autumn of 2016 a series of US diplomats began suffering unexplained losses of hearing, according to officials with knowledge of the investigation into the case. Several of the diplomats were recent arrivals at the embassy, which reopened in 2015 as part of President Barack Obama’s re-establishment of diplomatic relations with Cuba. Some of the US diplomats’ symptoms were so severe they were forced to cancel their tours early and return to the United States, officials said. After months of investigation US officials concluded that the diplomats had been attacked with an advanced sonic weapon that operated outside the range of audible sound and had been deployed either inside or outside their residences.
US officials told the Associated Press that about five diplomats, several with spouses, had been affected and that no children had been involved. The FBI and Diplomatic Security Service are investigating.
Cuba employs a state security apparatus that keeps many people under surveillance and US diplomats are among the most closely monitored people on the island. Like virtually all foreign diplomats in Cuba, the victims of the incidents lived in housing owned and maintained by the Cuban government.
However, officials familiar with the probe said investigators were looking into the possibilities that the incidents were carried out by a third country such as Russia, possibly operating without the knowledge of Cuba’s formal chain of command. Nauert said investigators did not yet have a definitive explanation for the incidents but stressed they take them “very seriously,” as shown by the Cuban diplomats’ expulsions.
