A majority of U.S. intelligence agencies have reaffirmed in an updated assessment that it is "very unlikely" that a foreign adversary was responsible for so-called Havana Syndrome ailments, a U.S. intelligence official said on Friday.

A new report from U.S. intelligence finds no evidence linking a foreign power to the mysterious “Havana syndrome” injuries experienced by U.S. personnel.

A report from the intelligence community released Friday maintains its conclusion that a foreign adversary is not behind the mysterious ailments plaguing government workers, but it opened the door to the possibility overseas actors have developed the capability to do so.
