Doctors reported seeing changes in the brain matter of United States officials' and their spouses' brains after an incident, which Secretary of State Rex Tillerson described as “targeted attacks,” left them feeling ill in Cuba.
Initial reports indicated that victims experienced hearing loss and cognitive difficulties, but a Wednesday report from the Associated Press revealed the alleged attack might have altered the white matter tracts responsible for communication between brain cells.
U.S. officials initially suggested someone carried out the attack with a sonic weapon, but they reportedly backed away from that assessment. Officials said the loud, mysterious noise heard in Cuba might have been the byproduct of what actually caused the damage rather than a weapon itself.
Although Cuba's government denied any involvement in the incident, the Trump administration blamed it for failing to stop the attack and told 15 Cuban diplomats to leave the nation's embassy in Washington, D.C.
Victims reported hearing a high-pitched chirp, although some heard nothing even though they slept in the same room as those affected.
While doctors are unaware of the long-term consequences, those treating the victims will likely discuss their findings in an article for the Journal of the American Medical Association.
