It’s not just Germany that is currently experiencing a wave of sabotage. New attacks on the infrastructure are also feared in Denmark.

The Danish secret service has warned of Russian acts of sabotage in the Scandinavian country. Moscow “actively prepare acts of sabotage aimed at the defense industry in Denmark the head of counterintelligence at the Danish secret service PET, Emil Graesholm, told the daily Berlingske. The services of the Russian head of state Vladimir Putin are therefore trying to recruit “normal Danes”. Experts speak of disposable agents.

According to Graesholm, the orders of the Russian authorities can consist of taking photos, checking the access and security conditions around a facility and reporting on them. “We talk about these methods because they don’t have to look like a spy film,” he emphasized in an interview with Berlingske.

The Danish authorities also warn. It is “fundamental” that the Danish defense industry “takes the necessary security measures so that it is able to protect itself,” Graesholm told the Danish television station TV2. “Many players in this area are already actively working on it,” he added.

The PET secret service had already stated in 2024 that the Russian threat against Denmark had increased. Moscow was recently accused of increasing its acts of sabotage against European supporters of Ukraine. On Tuesday she did Federal Government Russia for the attempted attack on the Airport Leipzig/Halle responsible and imposed punitive measures.
