The CIA has evacuated a US intelligence officer who was serving in Serbia due to experiencing symptoms related to the mysterious "Havana Syndrome," the US media reported.
This is the most recent case of the neurological attacks which the US administration claims have targeted the country’s spies and diplomats stationed in overseas locations.
The illness, which has come to be known as “Havana Syndrome”, was first reported by American diplomats in Cuba in 2016.
US politicians, researchers and pundits have speculated that the mysterious condition was caused by electronic weapons.
The illness’ symptoms purportedly include headaches, nausea, memory loss, vertigo, bloody noses and hearing strange sounds.
"We take each report we receive extremely seriously and are working to ensure that affected employees get the care and support they need," a State Department spokesman said of continued attacks on American officials.
Over the past months, the US embassy in the Austrian capital has become a hotbed of what the CIA calls “anomalous health incidents.”
The CIA even removed its top officer in Vienna last week over what it called an insufficient response to a growing number of mysterious health incidents at the US embassy there.
The US administration, however, still doesn't know who is behind the attacks or have certainty about how they're being carried out.
"In terms of have we gotten closer? I think the answer is yes – but not close enough to make the analytic judgment that people are waiting for," CIA Deputy Director David Cohen said earlier this month.
Meanwhile, a panel of Cuban scientists have rejected the claims by the US officials, reiterating that there is "no scientific evidence” regarding such attacks.
"We conclude that the narrative of the 'mysterious syndrome' is not scientifically acceptable in any of its components," the panel said in a report published on state-run website Cubadebate on Sep. 13.
