First, it’s not the entire staff...just five foreign service workers, and their spouses....BUT not the kids. If it were the entire embassy, then this would make perfect sense on the Cubans. It’s only five affected, and those guys got shorten tours...leaving early.
Just a wild suggestion here, but I might ask...are all five couples lodged in the same building connected to the embassy, and is there a SCIF in the building? Some idiot in security might have approved some sonic device for security purposes (new design)...and it’s their own system causing this issue.
If you read the story put out....you have to assume that they all (with the spouses affected) live in the same building. Oddly....none of their kids showing any issues.
