HELSINKI (AP) — The Norwegian Defense Ministry says that Russian forces in the Arctic disturbed GPS location signals during a recent large NATO drill in Norway.

The ministry says that Norway's Foreign Ministry earlier had raised the issue with Russian authorities.

In an email Tuesday to The Associated Press, the ministry said it "was aware that that jamming has been recorded between Oct. 16 and Nov. 7 from the Russian forces" on the Arctic Kola peninsula.

NATO's huge exercise Trident Juncture that included soldiers from 31 countries, was staged in Norway from Oct. 25 to Nov. 7.

The jamming of the location signals is not believed to have caused any accidents.
