Poland deploys extra forces at Kaliningrad border in security operation

Poland has launched a large-scale security operation along its border with the Russian exclave of Kaliningrad, with extra police, counterterrorism units and troops from the elite military special forces unit GROM deployed in the country's northeast, national police chief Marek Boroń said. Prime Minister Donald Tusk said the rapid deployment may have thwarted a possible act of sabotage or provocation aimed at the NATO member.

Key facts

• The operation runs from Monday until at least 8 November 2026, according to national police chief Marek Boroń.
• Additional police, counterterrorism units and GROM special forces are deployed in the Warmia-Masuria and Podlaskie regions.
• A special command centre has been set up at national police headquarters to coordinate the effort.
• Polish and allied intelligence warned of possible sabotage and provocations in the first half of November, particularly along the Kaliningrad border.
• Polish authorities had not published evidence of specific sabotage or attack plans by Tuesday afternoon.

What is happening at the border?

Police said the aims of the operation are to protect the public, detect suspicious activity early and prevent attacks on critical infrastructure. Tusk said suspicious movements were observed overnight near Kaliningrad, including individuals carrying flashlights close to the border area, and that the fast response by Polish security forces may have stopped an unspecified provocation this week.

Polish and allied intelligence services had warned of possible sabotage operations and provocations during the first half of November, including possible border incursions by armed groups. Those warnings had already put domestic security agencies on high alert before the additional forces were moved to the northeast.

Which areas are affected?

The deployments are concentrated in the northeastern regions of Warmia-Masuria and Podlaskie, along the border with Kaliningrad. Russia's exclave is bordered only by NATO members Poland and Lithuania and by the Baltic Sea. Immediately to its east lies the Suwałki Corridor, the only land border linking the Baltic NATO states with the rest of the alliance, where Poland and Lithuania share a short border between Russian and Belarusian territory.

Why is this happening?

Tusk said intelligence had pointed for weeks to possible "acts of diversion or more serious provocation" against the European Union, including the intrusion of armed individuals into Polish territory. Speaking at a joint news conference with Lithuania's prime minister on 13 October, he referred to a recent conversation with NATO Supreme Allied Commander Alexus Grynkewich that reinforced his concerns about threats of sabotage, including possible provocations involving aircraft or attacks on border crossings.

The alert follows months of sabotage, air incursion and other low-level incidents across Europe largely blamed on Russia, including a fire at a Polish drone factory in August and an arson attack on a Starlink satellite ground station that Polish officials blamed on Russia in September.

What this means for travellers

Travellers in the Podlaskie and Warmia-Masuria regions, including the area around the Suwałki Corridor, should expect a heavier security presence along the Kaliningrad border while the operation is running. The operation is scheduled to continue at least until 8 November 2026; the source does not state whether any border crossings or roads have been closed.

Anyone planning to travel near the border in the coming days can check for updates from Polish authorities before setting out, as the security measures remain active through the period covered by the intelligence warnings.
