Nordic Security Brief: Spy Charges, New Sanctions and Forces Across Borders

October 20, 2026

Denmark: Espionage case targets a company fighting drones

Two men aged 18 and 21 appeared in court in Aalborg on Tuesday, accused of photographing a Danish defense company for Russian intelligence.

The case concerns MyDefence, a company in Nørresundby that develops equipment to detect and counter drones. Prosecutors allege that photographs taken on October 19 were transmitted through Telegram and intended for Russian intelligence. Both men deny wrongdoing.

North Jutland Police is investigating alongside the Danish Security and Intelligence Service, known as PET. Prosecutors requested a closed hearing. The court’s final decision on pretrial detention remained unconfirmed at the time of this report.

PET also warned that seemingly simple photography assignments offered by strangers through social platforms can form part of preparations for sabotage. The warning describes a wider recruitment method; the specific allegations against the two defendants concern the photography and transmission of information.

Greenland also featured in a major European policy announcement on Tuesday. The European Commission’s new Arctic strategy includes plans for a secure subsea cable connecting Greenland with Europe, stronger satellite coverage and a proposed Arctic Cable Hub to support the protection, monitoring and repair of underwater infrastructure.

The strategy also proposes examining joint procurement and shared use of icebreakers. Funding and implementation remain subjects for further decisions.

Finland: Military reform would allow compulsory training abroad

Finland is preparing legislation that would allow conscripts and reservists attending refresher training to be ordered to exercises in Norway, Sweden and the Baltic region when the activity directly supports Finland’s defense.

The proposal would remove the requirement for separate consent for these training assignments. The government plans to submit its bill in November.

A separate arrangement would allow consenting reservists to undertake temporary service in NATO land-force missions. The draft also proposes a common ceiling of 200 refresher-training days, replacing limits that currently vary between categories of reservists.

Finland’s Security and Intelligence Service, Supo, meanwhile described how Russia uses international procurement networks to obtain goods for its state institutions and military industry.

The service identified Russia’s military intelligence agency, the GRU, as a central participant in planning and implementing sanctions evasion. Procurement chains can begin inside the European Union, with intermediaries and third countries concealing the eventual Russian recipient.

The comments provide a broader intelligence assessment following revelations about electronics exports routed through Finland. Supo confined its remarks to the general pattern and declined to discuss the individuals involved in that investigation.

The Finnish Army also announced eight major exercises extending into early December. Mighty Hammer, beginning October 23, will involve around 2,000 personnel, mainly reservists. Lightning Strike, starting October 30, will bring together approximately 4,100 participants, including forces from Norway and Sweden.

Later in the program, Lapland Steel will include Finnish Army and Border Guard personnel alongside allied troops, with a focus on cooperation with NATO’s forward land forces.

Norway: Russia restrictions take effect Wednesday

Norway announced further implementation of the European Union’s 21st sanctions package against Russia, with regulatory changes taking effect on October 21.

The measures include transaction restrictions covering another 33 Russian financial institutions and 22 banks or financial institutions in third countries. They also expand export controls and restrictions affecting Russian oil-related activity.

The criteria for designating vessels are being broadened to include ships servicing listed vessels or conducting ship-to-ship transfers with them. This extends the scope for action against the networks supporting sanctioned shipping.

Norway had already implemented the package’s individual, company and vessel listings in August. Tuesday’s announcement brings additional regulatory provisions into force.

Civilian preparedness also featured in a parliamentary statement by Åsmund Aukrust, Norway’s minister of international development. A Nordic health-preparedness group is examining a joint evacuation plan for health and social services, alongside work to make cross-border medical assistance easier.

That cooperation will continue during Norway’s Nordic presidency in 2027. The statement also addressed food supplies, essential services and closer cooperation between civilian and military authorities. Greenland, the Faroe Islands and Åland now participate in the expanded Haga cooperation on civil preparedness.

At home, the Norwegian Directorate of Health raised concerns about influenza vaccination among healthcare workers. A survey published Tuesday found that 55 percent intended to receive the vaccine. Health Director Cathrine M. Lofthus expressed concern about the findings as health services prepare for the winter influenza season.

Sweden: Maritime drones and emergency services cross borders

Sweden has brought four unmanned Saildrone surface vessels into operational service this month, strengthening maritime surveillance and the protection of underwater infrastructure.

The ten-meter vessels provide data around the clock. The Swedish Navy assigns their tasks, while the supplier’s personnel operate and monitor them.

Defense Minister Pål Jonson and Justice Minister Gunnar Strömmer will attend a demonstration in Nynäshamn on October 22. The initiative supports NATO’s Baltic maritime-security efforts, and its agreement through Nordic Defence Cooperation, or Nordefco, allows other Nordic countries to join.

Along the Norwegian border, the Grenskraft total-defense exercise is bringing together almost 2,000 people from around 40 organizations, including approximately 1,500 soldiers.

Police, ambulance services, firefighters, municipalities and military units are practicing their response to crises requiring cooperation across the border. Tuesday’s Händelse Nord exercise took place around Trysil and Malung-Sälen. Händelse Syd follows Wednesday around Eidskog and Eda.

The exercise will test how authorities work together during a security crisis and identify where laws, responsibilities and operating procedures complicate cross-border assistance.

Iceland: North Atlantic cooperation and a new security prison

Iceland highlighted its growing role in the Joint Expeditionary Force, or JEF, following a recent visit by its commander, Major General Olly Brown.

An announcement published Tuesday described discussions on security in the North Atlantic and Arctic, hybrid threats and the protection of critical underwater infrastructure.

The visit included air-policing operations and host-nation support at Keflavík. Iceland’s contribution also includes liaison personnel and expertise supporting maritime monitoring. Cooperation will continue through the forthcoming Lion Protector activity later this year.

Justice Minister Þorbjörg Sigríður Gunnlaugsdóttir also broke ground Tuesday for a new prison at Stóra-Hraun, designed specifically for high-security detention.

The fully funded first phase will provide 56 places, with the completed facility planned to accommodate 128 prisoners. Authorities link the project to the challenges posed by organized crime, the management of connections between prisoners, and the safety of staff and inmates. Rehabilitation is also part of the facility’s planned role.
