Polish officials warn NATO that Russia and Belarus are ‘weaponising’ migration at the Polish-Belarusian frontier

A hard winter sun glints off razor wire as an armoured column from Poland’s 18th “Iron Division” rumbles along the 521-kilometre border with Belarus. It is here, senior Polish commanders and diplomats told Fox News on 17 May 2026, that the next phase of European conflict is already under way. Warsaw accuses Moscow and Minsk of orchestrating flights from the Middle East, Africa and South-Asia to Minsk and Grodno, then funnelling the passengers westwards in organised groups. The tactic, Polish officials say, is designed to overwhelm border guards, sow political division inside the EU and test NATO’s resolve.

The campaign reached its first peak in 2021, when nearly 40,000 illegal crossing attempts were recorded. Although the number fell to just under 30,000 in 2025 and is lower so far this year, the Border Guard insists the threat has merely shifted: traffickers are now probing alternative routes through Lithuania, Latvia and even Finland.

In response, Poland has layered its frontier defences. A 5-metre steel wall finished in 2023 has been upgraded with motion sensors, thermal cameras and facial-recognition towers linked to a central command room in Białystok.



More than 4,000 troops back up the regular border service on rapid-reaction duties. Defence Minister Władysław Kosiniak-Kamysz argues that the pressure is part of a broader Russian “hybrid” tool-kit that also includes cyber-attacks, disinformation and sabotage. “For Poland this is war by other means,” he told reporters, noting that Warsaw now spends almost 5 percent of GDP on defence—by far the highest ratio in the Alliance.

For organisations and individual travellers needing clarity amid these shifting entry rules, VisaHQ’s dedicated Poland page (https://www.visahq.com/poland/) provides up-to-date visa requirements, secure online applications and concierge support. Leveraging this service can significantly reduce the administrative burden created by sudden ID checks or new biometric enrolment demands.

Foreign Minister Radosław Sikorski framed the issue for Washington: “If the eastern flank buckles, migrants do not stop in Warsaw, Vilnius or Riga. They keep moving—to Berlin, Paris and the United States.” Polish haulage, manufacturing and agribusiness groups support the security effort but warn that repeated six-month extensions of internal Schengen controls add millions of euros in compliance costs. Waiting times have tripled for just-in-time lorry traffic between Białystok and Hrodna, while airlines serving Chopin Airport face higher passenger-data requirements and random police checks on arrivals from Germany.

Multinationals with staff rotations through Warsaw are advising assignees to carry additional proof of residence and to allow extra time at land crossings. For mobility managers the message is two-fold. First, travel between Poland and its eastern neighbours will remain unpredictable well into 2027. Second, the migration stand-off is now embedded in NATO strategy, meaning that border security measures—ID checks on trains, passport stamps on the A2 motorway, and biometric enrolment at Warsaw airports—are likely to be semi-permanent. Companies should update corporate travel policies, build in longer lead times for posted-worker notifications and monitor Schengen-code exemptions that could affect work-permit holders transiting the region.
