Police in Germany are investigating an alleged 'sonic weapon' attack against US Embassy staff.
It began in August according to a report in Der Spiegel, and involves at least two cases of the so called 'Havana Syndrome'.
That's a range of symptoms such as headaches, dizziness, memory loss and nausea.
Worldwide, 200 cases have been reported with intelligence and diplomatic staff worst affected.
The CIA believes there's a 'very strong possibility' that they were caused deliberately.
