The threat of Russian sabotage in Europe has increased over the summer.
Teemu Liikkanen, head of counterintelligence at the Finnish Security and Intelligence Service (Supo), says the threat is real in Finland too, although there is no indication of any immediate danger.
"There is no reason to panic or become fearful. We should not go down that road. But we need to be prepared and ready," Liikkanen said on Yle's breakfast show on Monday.
In Finland, the targets most vulnerable to Russian sabotage are particularly the defence industry and activities supporting Ukraine.
Russia has carried out sabotage in countries supporting Ukraine for several years. Sabotage activity was noticeably quieter in 2025, but the threat has now increased again.
Jyrki Isokangas, a retired colonel and university lecturer at the University of Jyväskylä, said Russia is seeking to drive a wedge between Western countries and undermine support for Ukraine.
"Russia is trying to create an atmosphere in Western countries in which helping Ukraine is seen as something that you shouldn't or can't do," he added.
Isokangas does not, however, believe Russia wants to challenge Nato through military action.
Russia is believed to have been behind the arson attack on a Starlink satellite station in Poland last week.
President Alexander Stubb has meanwhile urged Finns to prepare themselves mentally for possible acts of sabotage.
