US Investigates Unexplained Health Incidents Among Diplomats In Vienna

The Biden administration is investigating a recent spate of mysterious health incidents reported by American diplomats and other government employees in Vienna, say US officials.

Some of the symptoms are similar to those first reported by US diplomats and spies in Havana, Cuba, in 2016 and 2017, for which no definitive cause has yet been determined.

US officials said more than 20 new cases are being looked at by medical teams at the State Department and elsewhere, including the Pentagon and the CIA.

"In co-ordination with our partners across the US government, we are vigorously investigating reports of possible unexplained health incidents (UHI) among the US Embassy Vienna community," the State Department said.

"Any employees who reported a possible UHI received immediate and appropriate attention and care."

Some believe the unexplained injuries, which include brain damage, are the result of microwave or radio wave weapons, but despite years of study, there is no consensus as to what or who might be behind the incidents or whether they are actual attacks.
