Canada pulls diplomatic families out of Cuba citing health concerns

Canada's government has ordered families of diplomats to return home from assignments in Cuba due to a mystery illness of unexplained symptoms, including dizziness, nausea, and difficulty concentrating.

The pattern: The U.S. ordered diplomats to come home from Cuba in the fall for a similar illness, but Canada says it is discounting theories that sonic attacks are the culprit. Canada's government writes that it represents "a new type of a possible acquired brain injury."
