Pentagon bought device through undercover operation some investigators suspect is linked to Havana Syndrome

The Pentagon has tested a device that investigators believe may be linked to the condition commonly referred to as Havana Syndrome, CNN has reported.

The Defense Department has been testing the device, which was bought during an undercover operation by the Department of Homeland Security, for over a year, the network reported on Monday, citing four anonymous sources briefed on the subject.

Newsweek contacted the Pentagon, the Central Intelligence Agency (CIA), and the Department of Homeland Security (DHS) via email outside of regular office hours on Tuesday.
