For more than 18 months, US diplomats have come down with similar illnesses that include mild brain damage and hearing loss after they claim to have heard unusual sounds. The incidents began in Cuba but reports have now spread to other countries. As authorities have ramped up efforts to treat any potential cases, almost 200 people have reportedly come forward to be tested.

The steady trickle of information about the strange case of attacks on US diplomats in Cuba through alleged "sonic devices" continues. On Thursday, the Associated Press released what it claims are recordings of the sounds that diplomats heard before experiencing mild brain damage and hearing loss. And you can listen to them!

Following a report yesterday that claimed US spies working under diplomatic cover were the primary target of mysterious "sonic device" attacks on US embassy personnel in Havana, American authorities have expelled 15 members of Cuba's diplomatic staff from its embassy in Washington.

It appears that the Trump administration has an opportunity to undo the reopening of diplomatic relations with Cuba -- just like it wanted to do. Following unexplained "covert sonic device" attacks on envoys from both the US and Canada that were stationed in Havana, the US State Department is pulling more than half of its staff out of Cuba, and warning travellers of potential danger.

The baffling story of US diplomats in Cuba suffering hearing loss and brain damage in some sort of covert "health attack" just gets stranger and more terrifying with every new report. The Associated Press has learned that victims' recollections and symptoms are even more varied and serious than we previously knew.
