Russia could launch a limited military attack against a NATO country in the coming months, Danish intelligence said, in one of the harshest warnings yet from Western security services. In a report released Thursday, the Danish defense intelligence service warned of a “low but increasing risk” that Russia could launch long-range attacks against NATO infrastructure supporting Ukraine, or carry out a limited incursion into a neighboring country with a small number of troops, potentially operating without insignia. The report came hours after a fire at a Starlink satellite station in central Poland was described by local authorities. as an “act of sabotage”. Krzysztof Gawkowski, Poland’s deputy prime minister, said the fire, which broke out overnight in the Masovian voivodeship, had been “deliberately designed to disable the station,” disrupting internet access for several institutions, including the Ukrainian military.

In recent weeks, several European intelligence chiefs have warned that Russia may be preparing more assertive actions to test NATO countries’ commitment to supporting Ukraine, although officials differ on how imminent such a move may be. Russia is expected to step up its hybrid attacks against European countries with “greater consequences” for those they target in the coming months, the Danes warned, including “Destructive cyberattacks that paralyze social functions, as well as sabotage attacks that carry a high risk of casualties.” “Russian military leaders are convinced that some NATO countries are directly involved in the war against Russia, not only by supplying Ukraine with weapons and intelligence, but by helping to guide missiles and drones,” the source said, speaking on condition of anonymity. “Therefore, they believe that NATO is already waging a hybrid war against Russia, and that Russia has the right to respond in kind.” The source added. “Hybrid attacks” are broad terms in general. They are used to describe non-military tactics aimed at pressuring or destabilizing an adversary, including cyberattacks, sabotage and disinformation. The goal of Russia’s actions would be to divert European resources from supporting Ukraine and deepen divisions within NATO if the alliance fails to agree on a collective response, the report added. The service believes it remains “highly unlikely” that Russia would launch an open invasion of a NATO country. in particular said that “it cannot be ruled out.” The Danish services said Russia could try to test NATO’s Article 5, which commits members to collective defense.
