As the U.S. government considers closing its embassy in Cuba, scientists remain baffled by the mysterious sonic weapon that was apparently used to target American diplomats in Cuba.
On Sunday, Secretary of State Rex Tillerson said that the U.S. is considering the closure of its embassy in the Cuban capital following a spate of unexplained incidents that have left American diplomats injured.
Of the 21 medically confirmed U.S. victims, some have permanent hearing loss or concussions, while others suffered nausea, headaches and ear-ringing. Some are struggling with concentration or common word recall, the Associated Press has reported.
Some victims felt vibrations or heard loud sounds mysteriously audible in only parts of rooms, leading investigators to consider a potential “sonic attack.” Others heard nothing but later developed symptoms.
