Another Canadian diplomat diagnosed with mysterious Cuba brain injury

Another Canadian diplomat in Havana has been diagnosed with a mysterious brain trauma that in 2016 starting afflicting Canadian and US officials in the Cuban capital, a senior official said Thursday.

The latest case, identified in the "early summer of 2018," brings the total number of afflicted Canadian diplomats and their family to 13.

Meanwhile a review of Canada's diplomatic presence in Cuba has been launched, a senior Canadian government official speaking on condition of anonymity told reporters.

"Medical testing has now confirmed that an additional employee has been affected by the unusual health symptoms," the official said.

"These are simliar to those previously experienced by diplomatic staff in Cuba as identified earlier this year." The official said in regards to the review that "all options to secure the health and safety of our diplomats in Havana are open," but offered few details.

The Canadians continue to receive care while a federal police investigation in collaboration with US and Cuban authorities remains open.

Canadian and US authorities had 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."
