Poland said it will deploy about 40,000 troops to its eastern border as it braces for the joint Russian‑Belarusian Zapad 2025 military exercises and responds to a series of drone incursions that Warsaw says violated its airspace.
Polish Prime Minister Donald Tusk described the situation as the most dangerous for the West since World War II and the government invoked Article 4 of the North Atlantic Treaty, signalling the start of consultations among NATO allies. The U.N. Security Council has agreed to hold an emergency meeting at Poland’s request to consider the drone incident, the foreign ministry said.
Deputy Minister of National Defence Cezary Tomczyk told Polish television that "Polish and NATO soldiers are needed to adequately respond to Zapad‑2025" and that "in the coming days, we will have about 40,000 soldiers at the border." Poland also said it had closed parts of its border with Belarus in anticipation of the exercises.
The Kremlin and Minsk are scheduled to hold Zapad‑2025 drills near Poland and Lithuania, with official organisers saying the exercises will not exceed 13,000 personnel. Analysts and some Western officials, however, warned that historical precedents, including the Zapad‑2021 exercises, have seen far larger force buildups and could mask broader mobilisation. Russian and Belarusian authorities have said they will invite observers from NATO countries.
Poland said the drone incursions occurred overnight between Tuesday and Wednesday, identifying 19 violations of its airspace and saying its forces shot down at least three drones. Polish officials released images showing damage to a house struck by a drone and displayed downed drone wreckage in parliament. Moscow denied responsibility and said some Russian strikes had targeted military facilities in western Ukraine but that Russia did not intend to hit targets in Poland. A senior Russian diplomat cited in Warsaw said the drones came from the direction of Ukraine.
Poland’s invocation of Article 4 — which allows any NATO member to request consultations when it perceives a threat to its territorial integrity, political independence or security — marked the eighth such request in the alliance’s history. NATO said it was "monitoring Russia’s activity very closely" and that it did not see an "immediate military threat against any NATO ally" while remaining vigilant.
Western leaders and NATO officials noted the risks posed by the timing and scale of the exercises. German Chief of Defence Carsten Breuer said NATO would "be on our guard" during the drills. Dutch Prime Minister Mark Rutte warned publicly about the potential for coordinated geopolitical tensions, and former NATO officials and analysts urged close scrutiny of force movements and equipment displayed during the exercises.
Analysts have pointed to satellite imagery and open‑source reporting indicating construction activity at a site near Minsk that was historically used to store Soviet strategic weapons. Some security experts said the site could be adapted to store strategic equipment or missile systems, including the Russian Oreshnik intermediate‑range system that Moscow has previously described as nuclear‑capable. Kremlin officials describe Zapad drills as defensive in nature; Western analysts say such exercises also provide Russia and Belarus an opportunity to rehearse large formations, logistics and the deployment of systems near NATO borders.
The Zapad series of exercises is held roughly every four years. The 2021 iteration coincided with a significant Russian force posture in Belarus months before the invasion of Ukraine in February 2022, a sequence that has heightened sensitivity in Warsaw and other capitals. Western militaries are conducting their own exercises in the region this month, including Poland‑led drills dubbed Iron‑Defender‑25, which the Polish government says will involve some 30,000 troops from Poland and allied countries to test deterrence and defence of Polish territory.
For NATO, the drills will be an opportunity to assess Russian capabilities, including electronic warfare and drone operations, and to observe whether Moscow can sustain large‑scale training after more than three years of conflict in Ukraine. Military analysts say an absence of expected capabilities during Zapad could indicate attrition or logistical strain, while the presence of systems such as intermediate‑range missiles near NATO territory would be closely watched.
Polish leaders emphasised that the troop deployments were defensive and intended to reassure the population and allies. Deputy Defence Minister Tomczyk said Warsaw had been preparing for Zapad‑2025 for months. Tusk told parliament that the drone incursions were a "provocation" and stressed the need for solidarity among NATO members. Poland’s foreign minister, Radoslaw Sikorski, said the U.N. meeting would be used to draw global attention to what Warsaw described as an unprecedented attack on a NATO, EU and UN member.
Moscow urged further consultations between military authorities and dismissed portrayals of the incident as an escalation. Russian defence ministry statements acknowledged strikes in western Ukraine in recent days but said they were not aimed at Polish territory.
The situation remains fluid as the Zapad‑2025 exercises proceed and NATO allies consult on next steps. Both sides have signalled an interest in observation and transparency, but the juxtaposition of large military manoeuvres and the recent cross‑border drone activity has intensified diplomatic and military attention across Europe.
