The authorities were still investigating who was responsible, he said. Mr Sipilä said: "It is possible that Russian Federation has been the disrupting party in this".
When asked to take a stance against reported Global Positioning System interference during the recent NATO drill Trident Juncture, the largest on Norwegian soil in decades, NATO Secretary General Jens Stoltenberg chose not to perpetuate speculations regarding Russia's involvement and refused to go into detail.
Kremlin spokesman Dmitry Peskov called Sipila's accusations "groundless", adding that Russian Federation is regularly accused of "all mortal sins".
Mr Silipa appeared to point the finger at the Russians during an interview with Finnish public broadcaster Yle, noting that the Kremlin "is known to possess such capabilities". "As a rule, these accusations are baseless".
A pilot with the regional Norwegian airline Wideroe reported a loss of Global Positioning System signals during a flight near Kirkenes, close to Norway's border with Russian Federation, at the start of November.
Moscow was angered by the huge exercise, which involved 50,000 troops from 29 North Atlantic Treaty Organisation countries, as well as Sweden and Finland.
Finnish Prime Minister Juha Sipila revealed on Sunday that air navigation services across the country had to issue traffic warnings due to the interruption last week, which is believed to have been deliberate.
"There are no security risks, we have good routines and this is not the first time we have experienced loss of signals", a Widerøe spokeswoman told the Barents Observer website.
"It's a message to all parties participating in the military exercise", he explained.
Finnish parliamentarians lined up on Friday to call for a robust response to the signal jamming, with defence committee chair Ilkka Kanerva telling YLE that the effect on civil aviation could have been "catastrophic".
The NATO Trident Juncture drill, which involved about 50,000 troops from over 30 countries, including formally non-aligned Sweden and Finland, took place from October 25 to November 7.
