"Incidents" in Cuba lead to hearing loss for U.S. diplomats

The United States has expelled two Cuban diplomats from Washington after U.S. officials stationed at the American Embassy in Havana "reported incidents which have caused a variety of physical symptoms," per the AP.

• The details: Some Americans posted at the embassy in Havana — who lived in housing owned and maintained by Cuba, as do all foreign diplomats — experienced mysterious symptoms that reportedly include potentially permanent hearing loss.
• The cause: Though the investigation is still occurring, American investigators believe there's a possibility that the Cuban government — or someone sympathetic — may have placed devices that emitted sounds outside the range of human hearing inside or around the homes of those affected.
• Why it matters: Trump already cancelled some portions of the détente that began under the Obama administration, and these allegations could cause the relationship to deteriorate further.
