Sonic attack on diplomats: At least six US diplomatic staff have been withdrawn from Havana since last autumn suffering from unexplained symptoms including hearing loss and dizziness, apparently as the result of some kind of “acoustic attack” on their Cuban government-owned homes, the US State Department has revealed. Officials declined to reveal the exact symptoms; however, they are reported to include at least one case of permanent hearing loss. Two Cuban diplomats have been expelled by the US in response. The US is investigating the possibility that a rogue element of Cuba’s intelligence establishment conducted the sonic attack with the aim of disrupting reconciliation efforts. Alternatively (and a more likely explanation, according to US intelligence sources), a new kind of eavesdropping technology may have gone awry, causing unintentional injury to the diplomats.
