WASHINGTON (NEWSnet) — U.S. intelligence agencies cannot link a foreign adversary to any of the incidents associated with so-called “Havana syndrome.”

The hundreds of cases of brain injuries and other symptoms reported by American personnel around the world.

The findings released Wednesday by U.S. intelligence officials cast doubt on the longstanding suspicions by many intelligence agents and diplomats around the world who reported cases of brain injuries and other symptoms.

The theory was that Russia or another country may have been running a global campaign to harass or attack Americans using some form of directed energy.

Officials say most of the cases investigated appear to have different causes from environmental factors to undiagnosed illnesses.

In some cases, the U.S. detected among adversarial governments confusion about the allegations and suspicions that Havana syndrome was an American plot.

Compensation has been approved for those who experienced the illnesses.
