Did Washington hide Moscow's responsibility for diplomats being infected with Havana Syndrome?. A press investigation accused the administration of US President Joe Biden of covering up Russia’s “involvement” in the spread of Havana Syndrome.

In 2023, officials estimated that about 1,500 American diplomats and military personnel had been infected in recent years in 96 countries with this mysterious disease. The investigation linked this disease to a Russian intelligence unit. It alleges that members of a specific Russian military intelligence unit - known as 29155 - targeted the brains of American diplomats with “directed energy” weapons.
