A Canadian NATO helicopter has crashed off the coast of Greece.

Several reports suggest a military chopper operating off the Canadian frigate HMCS Fredericton went missing earlier today.  Apparently, the helicopter was part of Operation Reassurance, a mission to end Russian interference in Central and Eastern Europe.

Greek State TV has reported debris and a body has been found but five other crew members are missing.

The Canadian Armed Forces have confirmed they have lost contact with the aircraft but no other details are available. A search and rescue mission is underway.
