Finland held a civil defence exercise in the central city of Kuopio on 2-3 September 2026, the largest in Europe since the end of World War II. Over 2,000 participants, including conscripts, volunteers and students, took part in the drill, which simulated cyberattacks disrupting power and water supplies and the threat of missile strikes from Russia. The exercise used a sports hall converted into a rock-hewn shelter designed to withstand nuclear or biological attacks. Finnish conscripts in hazmat suits measured radiation levels during the simulation, as reported by the Associated Press.

The Finnish Security and Intelligence Service investigated drone sightings and reflective stickers found on infrastructure but concluded there was no evidence of Russian sabotage. Savon Voima, a Finnish energy company, reported a rise in cyberattacks since the 2022 invasion of Ukraine and the discovery of unexplained stickers on vulnerable parts of its network. The company’s CEO, Juha Räsänen, said an explosion at those sites could have destroyed a dam, though no perpetrators were identified.

How the reports diverged on Russia’s role

The left-rated reports, including the Associated Press, framed the exercise as a response to Russia’s broader campaign of sabotage across Europe, citing Western officials who linked fires, drone attacks and infrastructure strikes to Moscow. The centre-rated digests, such as those from Euronews and Military.com, carried the same claim but did not lead with it. The right-rated digests, including Breitbart and Protothema, described the drill as a direct preparation for a potential Russian attack, with Protothema stating that citizens were "training for an attack by Russia". None of the digests from any side disputed the exercise’s scale or the threats it addressed.

What the coverage left out

None of the right-rated digests mentioned the Finnish Security and Intelligence Service’s conclusion that drone sightings and reflective stickers were likely unrelated to sabotage. The centre-rated digests omitted the historical context of Finnish-Soviet conflicts, including the veterans’ accounts carried by the Associated Press. Only the Associated Press’s full report included the Ukrainian student’s perspective on the value of civil defence training.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

11 rated outlets

  • The seven left-rated digests and the Associated Press’s full report led on the exercise’s scale and the historical context of Finnish resilience. The Associated Press quoted Finnish veterans recalling Soviet bombings during World War II and a Ukrainian student who sheltered in a stairwell during the 2022 invasion. The report also included the Finnish Security and Intelligence Service’s statement that drone sightings and stickers were likely unrelated to sabotage. Helsingin Sanomat’s digest noted the shelter’s capacity constraints, reporting that less than one square metre of space was allocated per person.

  • The seven centre-rated digests, including those from Euronews and The Hill, focused on the exercise’s technical aspects and the immediate threats it addressed. Euronews repeated the claim that Russia was conducting a campaign of sabotage across Europe, while My Mother Lode and Washington Top News led with the shelter’s design and the conscripts’ role in measuring radiation. None of the centre-rated digests quoted Finnish veterans or Ukrainian perspectives, and only VRT’s digest mentioned public sentiment, citing a participant who said, "We underestimate the risk of attacks."

Right

10 rated outlets

  • The seven right-rated digests, including those from Breitbart and La Razón, framed the exercise as a direct response to Russia’s aggression. Breitbart and tippinsights led with the shelter’s nuclear-biological protection, while La Razón described the drill as "Finland at war" and emphasised the 72-hour survival scenario. Korrespondent.net and Iefimerida explicitly linked the exercise to a "war with Russia", with Iefimerida’s digest stating that the drill was based on a "particularly worrying scenario". None of the right-rated digests mentioned the Finnish Security and Intelligence Service’s findings on drone sightings or stickers.

Questions about this coverage

Of the 34 outlets on this story carrying a published leaning rating, 32% are rated left, 39% are rated centre, 29% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 63. The sections above set out what each side emphasised, in its own terms.
Is Finland holds largest civil defence exercise in Europe since 1945 amid… left or right?
Neither side dominates it. Of the 34 rated outlets on this story, 32% are rated left, 39% are rated centre, 29% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Finland holds largest civil defence exercise in Europe since 1945 amid… biased?
Finland holds largest civil defence exercise in Europe since 1945 amid Russia tensions is one event reported by 63 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Finland holds largest civil defence exercise in Europe since 1945 amid…?
63 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.

What threats did the Finnish exercise simulate?
The exercise simulated cyberattacks disrupting power and water supplies and the threat of missile strikes from Russia. Participants rehearsed sheltering in a rock-hewn bunker designed to withstand nuclear or biological attacks, with conscripts measuring radiation levels during the drill.
Did Finnish authorities find evidence of Russian sabotage?
The Finnish Security and Intelligence Service investigated drone sightings and reflective stickers on infrastructure but found no evidence of Russian sabotage. Savon Voima, an energy company, reported increased cyberattacks and unexplained stickers on vulnerable sites since 2022.
Which outlets linked the exercise directly to Russia’s actions in Ukraine?
Right-rated digests, including Breitbart and Protothema, framed the exercise as a direct response to Russia’s aggression, with Protothema stating that citizens were "training for an attack by Russia".
