People for the Ethical Treatment of Animals on Monday implored the U.S. military to reinstate a ban on the intentional wounding of animals in experiments and to stop radiation testing in an attempt to determine the cause of the mystery ailment popularly known as Havana syndrome" that has afflicted U.S. government officials posted at diplomatic facilities in Washington, D.C. and several foreign countries. PETA argues that the military's decision to use live animals in testing related to Havana syndrome is "counterproductive" due to biological differences between humans and species subjected to the experiments, as well as the widespread availability of non-wounding research methods and the likelihood that radio frequency waves did not cause the mysterious ailment. The U.S. government has a long history of radiation experiments not only on animals but also on human beings. Scores of institutions, including some of North America's most prominent universities, laboratories, and hospitals hosted government and military experimentation on both volunteers and unwitting test subjects in the MK-ULTRA mind control experiments and other highly unethical and sometimes deadly programs. People suffering from Havana syndrome"so named because it was first identified by U.S. and Canadian diplomats and embassy staff in the Cuban capital"experienced what The Lancet described as "an abrupt onset of unusual clinical symptoms."
