Besides, the jamming affected air traffic in Norway.
“Pilots in Finland and Norway lost GPS navigation signals during recent NATO's large-scale Trident Juncture exercise near Russia's western border,” the news agency says.
Juha Sipila, the Finnish Prime Minister, said that Moscow was likely to blame for the disruption.
"Technology-wise, it's relatively easy to disturb a radio signal, and it's possible that Russia was behind it. We will investigate, and then we will respond. This is not a joke, it threatened the air security of ordinary people," he was quoted as saying.
Sipila noted that this incident would be treated as a breach of Finnish airspace.
“The goal of the alleged Russian interference was "to demonstrate the capabilities for such actions”,” the statement reads referring to the Prime Minister.
