US says Cuba must investigate ‘health attacks’ on diplomats

The United States said Friday it holds Cuba responsible for investigating an apparent sonic attack that left several of its diplomats in need of medical treatment.

Secretary of State Rex Tillerson said the US mission had not been able to determine who was behind what he called "health attacks" on its staff.

But he warned, “We hold the Cubans responsible just as every host country has a responsibility for safety and security of diplomats in their country.”

On Thursday, Canada revealed that one of its diplomats had also fallen victim to the mysterious attack. Canadian officials say the attack seemed to have been carried out with some kind of sonic device.

The Cuban government has denied any involvement, and says it has launched an intensive investigation into the incidents.
