‘Havana syndrome’ linked to Russian unit, media investigation suggests

US diplomats may have been targeted by Russian sonic weaponry, say The Insider, Der Spiegel and CBS’s 60 Minutes

The mysterious so-called Havana syndrome symptoms experienced by US diplomats in recent years have been linked to a Russian intelligence unit, according to a joint media investigation released on Monday.

Havana syndrome was first reported in 2016 when US diplomats in Cuba’s capital reported falling ill and hearing piercing sounds at night, prompting speculation of an attack by a foreign entity using an unspecified sonar weapon.
