A mysterious illness that has affected American diplomats in recent years has been linked to a Russian intelligence unit. Diplomats stationed worldwide experiencing symptoms akin to "Havana Syndrome," including unexplained dizziness, may have been targeted by Russian sonic weaponry, as per a joint investigation by The Insider, Der Spiegel, and CBS's 60 Minutes. Moscow has denied the allegations, while US officials previously downplayed the likelihood of foreign intervention.
