Cuba responsible for attack on US embassy staff: Trump

President Donald Trump today said he believes Cuba was responsible for the mysterious illness that afflicted US diplomats stationed in Havana.

"I do believe Cuba's responsible. I do believe that. And it's a very unusual attack, as you know. But I do believe Cuba is responsible," Trump said at an impromptu news conference at the White House.

Trump did not offer any further details.

The state department so far has refrained from blaming Cuba for the mysterious attack on its personnel in Havana resulting in several of its diplomats falling ill.
