The Canadian military has lost contact with one of its helicopters in the Mediterranean

The Canadian military says it has lost contact with one of its helicopters in the Mediterranean.

In a statement, the military says the aircraft from HMCS Fredericton went missing during an exercise off the coast of Greece.

It says a search-and-rescue operation is underway.

NATO spokeswoman Col. Juanita Chang earlier confirmed an incident involving a helicopter from a ship under NATO command.

Chang did not reveal the nationality of the aircraft or vessels.

HMCS Fredericton left Halifax for a six-month deployment around Europe in January with one of the Royal Canadian Air Force's new Cyclones on board.
