(CNN)The Russian military jammed GPS signals during a major NATO military exercise in Norway that involved thousands of US and NATO troops, the alliance said Wednesday, citing the Norwegian government.

The NATO exercise, Trident Juncture, concluded Sunday and involved some 50,000 personnel. It was labeled the alliance's largest exercise since the Cold War. Non-NATO members Finland and Sweden also participated in the exercise.
A spokesperson for the Norwegian ministry of defense acknowledged the jamming to CNN, which it said took place between October 16 and November 7, and said it would defer to the Ministry of Foreign Affairs on further questions to Russian authorities
