The U.S. intelligence community says it’s “very unlikely” that a foreign enemy is to blame for Anomalous Health Incidents (AHI) known as “Havana Syndrome” that are purportedly troubling American government personnel.

Havana syndrome is characterized by symptoms such as headaches, memory, and cognitive issues, hearing and vision loss, and dizziness caused by unexplained brain damage.
