Noises linked to mysterious injuries among US diplomats in Cuba were most likely caused by crickets — not microwave weapons — according to a declassified scientific review commissioned by the US State Department and obtained by BuzzFeed News.

The State Department report was written by the JASON advisory group, an elite scientific board that has reviewed US national security concerns since the Cold War. It was completed in November of 2018, two years after dozens of US diplomats in Cuba and their families reported hearing buzzing noises and then experiencing puzzling neurological injuries, including pain, vertigo, and difficulty concentrating.
