Why some US officials see new indications Russia could be behind Havana Syndrome

U.S. suspicions are rising that a Russian GRU-led attack cell is conducting pulsed radio frequency or microwave attacks against U.S. personnel, which is resulting in the so-called Havana Syndrome.

Contemporary reports of the syndrome were first reported by U.S. diplomats and intelligence officers in Havana, Cuba, in 2016. Many more U.S. personnel across the globe have since reported Havana Syndrome symptoms, which include aural distortions, severe headaches, loss of balance, and nose bleeds. Numerous affected CIA, State Department, and U.S. military attaches have been diagnosed with traumatic brain injuries as a result of their exposure.
