Havana syndrome mystery persists: CIA officers report attacks, cover-up allegations

A decade after the first reported cases, dozens of CIA officers continue to suffer from unexplained symptoms consistent with possible directed-energy attacks, with new incidents such as a 2019 London case. The cause remains disputed—either mass psychogenic illness or a covert weapon—and allegations of official cover-up persist. This matters because unresolved attacks on US intelligence personnel carry diplomatic and national-security implications, especially if a foreign actor is responsible.
