CIA officer's mystery illness in India: What's Havana Syndrome?

Earlier this month, when director of US spy agency CIA (Central Intelligence Agency) William J. Burns visited India, a member of his delegation reportedly experienced symptoms consistent with a mysterious illness called the Havana Syndrome. Burns was in Delhi to talk to National Security Advisor Ajit Doval about the Afghanistan situation with regard to Taliban's takeover. Subsequently, he went to Pakistan and met Army chief General Qamar Javed Bajwa. A CNN report said that only around 300 cases of the illness have been reported so far - all among US officials like spies and diplomats. The first case was seen in Cuba in 2016. Those affected complained of hearing buzzing sounds or piercing squeals which do not stop even if the patient's ears are covered. Others experienced an intense pressure on their skulls. Dizziness and fatigue were also reported. The US has launched a mega investigation to pinpoint the cause of the illness, and also identify those behind the acts of aggression. While the cause of the condition is unknown yet, there is speculation that it may be caused by microwaves. The scale of the US operation has been compared to the hunt for 9/11 mastermind and Al Qaeda chief Osama bin laden. Watch the full video for more.
