For years, reports of individuals connected to the U.S. government suffering from severe and often unexplained brain injuries surfaced every few months. Victims described debilitating ear pain, muscle cramps and even bone deterioration, but many said they were never given a clear explanation for what caused their symptoms.
A new investigation by CBS's 60 Minutes noted that the injuries may be linked to a previously unknown weapon that the U.S. military later obtained overseas and has quietly tested on animals at a U.S. military base, according to details of a classified U.S. intelligence mission obtained by the outlet.
