At least nine Americans at the U.S. Embassy in Guangzhou, China, were evacuated after what appears to have been a sonic attack.
The individuals complained of strange aural sensations, and more than 250 people connected to the diplomatic mission also received medical evaluations, according to The Wall Street Journal.
According to a health alert from the U.S. Embassy and Consulates in China, “The State Department received medical confirmation that a U.S. government employee in China suffered a medical incident consistent with what other U.S. government personnel experienced in Havana, Cuba.
“As a result of additional voluntary medical screenings, the Department has sent other individuals to the United States for further evaluation.”
The alert includes a request for any personnel or their families who experience symptoms, including “dizziness, headaches, tinnitus, fatigue, cognitive issues, visual problems, ear complaints and hearing loss, and difficulty sleeping,” to reach out for medical evaluation and possible treatment.
The medical evacuations follow a series of similar incidents that have impacted U.S. diplomats in China and in Cuba. Secretary of State Mike Pompeo announced on June 5 that he requested a “multi-agency response” to the “unexplained health incidents that have affected a number of U.S. government personnel and family members stationed overseas.”
In China, a U.S. Embassy employee in Guangzhou allegedly suffered a mild traumatic brain injury after hearing a vague and abnormal sound, according to a May 23 alert.
In Cuba, at least 16 U.S. government employees were affected by alleged sonic weapons, according to the U.S. State Department on Aug. 24.
Robert J. Bunker, adjunct research professor at the Strategic Studies Institute at the U.S. Army War College, told The Epoch Times in a previous interview that sonic weapons have long been in development, and fall under the broader category of directed energy weapons (DEW), alongside electromagnetic weapons. He said, “Like gun, missile, and bomb technologies, DEW can be utilized against people, material, and infrastructure.”
