U.S. intelligence has found no evidence linking a foreign power to the mysterious “Havana syndrome” injuries reported by some U.S. diplomats and other government personnel, though two agencies now say it's possible a foreign adversary may have developed or even deployed a weapon responsible for the injuries.
The conclusion, which echoes early investigations, comes from a review conducted by seven different intelligence agencies who examined cases of brain injuries and other symptoms reported by American diplomats and other military and government personnel who have raised questions about the involvement of a foreign adversary.
