(QHA) -

The authorities of the United States and Canada have canceled the Vigilant Eagle joint military exercise with Russia due to the situation in Ukraine.

North American Aerospace Defense Command (NORAD) spokesman Sgt. Charles Marsh told this to U.S. newspaper Fairbanks Daily News-Miner.

He said that the decision to suspend the exercise, at least for 2014, had been taken by U.S. Department of Defense officials and Canadian Prime Minister Stephen Harper.

Since 2007, NORAD and the Russian Federation Air Force had cooperated on the "Vigilant Eagle" exercise. Typically, exercises have been held in August or September near Alaska. The most recent iterations involved fighter jets intercepting a mock hijacked passenger airliner passing from Russia airspace into Alaska's, or vice versa.
