The US State Department has evacuated several of it’s diplomats from their posting in China after individuals reported experiencing health issues similar to those that affected diplomats in Cuba in 2016.

The illnesses involve headaches, nausea, hearing loss and cognitive issues and have been described as some sort of sonic attack.

Some reported hearing noises and sensations before the symptoms began, like marbles bouncing off the floor, while others reported nothing.

These most recent reports, which first began to emerge a few weeks ago, come from the southern Chinese city of Guangzhou.

But now US Secretary of State Mike Pompeo has announced the formation of a task force that will investigate the issue.

The Chinese Foreign Ministry said the government investigated one incident that occurred weeks ago in May but wasn’t informed by the US of any subsequent attacks and would be willing to investigate further if the US communicates the issue to them.

The attacks in Havana in 2016 resulted in a diplomatic rift between the US and Cuba, that lead to the expulsion of Cuban diplomats from the US and the withdraw of their own staff from the country, due to what it called an inability to protect its diplomats.

The protection of diplomats is required under the Vienna Convention, something that China said it was serious about upholding.

It isn’t clear yet how the US will respond to these most recent attacks.
