A newly obtained declassified report prepared for the director of national intelligence by a panel of experts appears to show conclusively that "Havana syndrome" — a cluster of unexplained symptoms experienced by diplomats and government personnel abroad — is not a naturally occurring health problem. It does not reach any conclusions about who or what may be responsible, but suggests that an unknown device or weapon using "pulsed electromagnetic energy" remains a plausible explanation.
The document was declassified after the James Madison Project, a nonprofit dedicated to reducing government secrecy, sued to obtain further information on "Anomalous Health Incidents" or AHIs, the official term used to designate the syndrome.
