The United States reduces the number of its embassy staff in Ukraine

American media reported that the Central Intelligence Agency (CIA) ruled out the so-called “Havana Syndrome” as a result of a campaign launched by a country hostile to Washington.

The media NBC NewsAnd New York times s Politico They cited CIA officials who reported that most cases of so-called Havana syndrome could be explained by environmental causes, undiagnosed medical conditions, or stress, rather than the actions of a foreign power.

Describing the study’s interim findings, CIA officials said that most of the 1,000 cases reviewed by US researchers are explainable and show that the mysterious disease is unlikely to have been caused by Russia or another foreign adversary.

Reports indicated that the CIA did not rule out foreign involvement in about twenty cases that are still unexplained and continue to be investigated.

In addition to these 24 cases, a large number of other unexplained cases remain, he said The New York Times.

US diplomats stationed in various countries have suffered from what’s called “Havana syndrome,” which causes symptoms similar to those of brain damage, dizziness, headaches, and an inability to concentrate.

The case first came to light in 2016 after dozens of diplomats from the US Embassy in Havana, Cuba, complained about their illness.

The study’s interim results disappointed some of those who fell ill, with a group of victims saying the CIA assessment “cannot and should not be the last word on the matter,” according to a statement carried by the newspaper.

US Secretary of State Anthony Blinken, at a press conference from Germany, responded to a question about the report by saying that the US government will continue to investigate the possible cause of the abnormal health incidents that affected US diplomats.

“We’ve worked overtime to try to understand what happened, and who might be responsible while we do everything we can to care for our affected colleagues and to protect people,” Blinken said.
