New reporting from The Insider forensically links Russia’s GRU military intelligence service to so-called “Havana Syndrome” radio frequency/microwave weapon attacks on U.S. government and military personnel in America and around the world. Symptoms of Havana Syndrome center on neurological conditions, including dizziness, an extreme sense of pressure in the head, unsteady gait, auditory problems, and headaches.

Sunday’s developments are big. Working with CBS News’s 60 Minutes and Der Spiegel, The Insider has collected evidence linking specific GRU officers and documents to RF/MW activities and specific global locations where U.S. personnel have reported Havana Syndrome symptoms. 60 Minutes interviewed the Defense Department’s former lead investigator for Havana Syndrome, Greg Edgreen, who stated his high confidence that Russia is responsible.
