WASHINGTON – It is a mysterious episode seemingly ripped from the pages of a Cold War spy novel.
In recent months, several U.S. and Canadian diplomats posted in Havana have reported experiencing unusual medical symptoms, including impaired hearing, sometimes so severe that they had to return home.
News of the ailments surfaced this week when the State Department announced that it had expelled two Cuban diplomats from Washington because of an "incident" in Havana that harmed U.S. personnel there.
That came despite vastly improved relations between Washington and Havana since restoration of diplomatic relations under former President Barack Obama.
On Thursday, the Canadian government added its voice.
Canadian officials "are aware of unusual symptoms affecting Canadian and U.S. diplomatic personnel and their families in Havana," the Canadian global affairs ministry said in a statement.
It said Canada was working with U.S. and Cuban authorities to "ascertain the cause."
U.S. State Department spokeswoman Heather Nauert would not provide details except to say the episode had caused medical but noncritical problems for an unspecified number of U.S. Embassy personnel based in Havana.
