Canada is slashing staff at its Cuba embassy after another diplomat was diagnosed with a mysterious brain injury that has affected several dozen North American envoys to the island, the government announced Wednesday.
The new case brings to 14 the number of Canadians -- alongside 25 Americans -- who have reported unexplained symptoms from dizziness, fatigue, headaches, hearing and vision complications, to loss of balance, nausea and an inability to concentrate.
Canadian public broadcaster CBC said just eight officials would be left at the embassy.
Canadian and US authorities initially suspected an attack using some sort of acoustic weapon, which led to heightened diplomatic tensions between Washington and the Caribbean island nation.
But Ottawa later concluded that to be "unlikely."
