Canadian diplomats who were in Havana during an alleged sonic weapons attack in April 2017 claim they suffered injury, yet have been abandoned by their government.
The incident appears to be part of a series of attacks that injured U.S. diplomats in Havana, Cuba, and in Guangzhou, China. A health alert from the U.S. Embassy in China warns embassy personnel of the incident, and says that if they or their families experience a range of symptoms to seek medical evaluation or treatment.
