New intelligence has led two US intelligence agencies to conclude that it’s possible a small number of mysterious health ailments colloquially termed as Havana Syndrome impacting spies, soldiers and diplomats around the world may have been caused by a “novel weapon” wielded by a foreign actor,

New intelligence about weapons research by American adversaries opens the possibility of a foreign actor behind the mysterious incidents that have injured hundreds of U.S. personnel serving overseas.

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 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.

Two agencies say U.S. adversaries might have developed a device that could cause a range of symptoms.

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.

Contradicting what U.S. spy agencies have publicly said, senior National Security Council officials told a group of Havana Syndrome victims in a meeting at the White House that they have seen information that undercuts the intelligence community’s assessment that no foreign adversary was behind the incidents.

A new report says two of seven US intelligence bodies believe foreign actors could be able to use radio frequency technology.
