(Credit: AP Photo/Ismael Francisco, Cubadebate) Secretary of State Rex Tillerson said Sunday that his department has considered closing the U.S. Embassy in Cuba following a series of “health attacks” against U.S. diplomats, the Associated Press reported Sunday. In the past nine months, 21 U.S. employees and family members in Havana have suffered mysterious injuries ranging from hearing loss and concussions to headaches and ear-ringing. While the Americans who suffered from the injuries worked in the embassy in Havana, the attacks did not occur on the recently opened site.
