A 27 February 2026 investigative report alleges that Russian engineers are digging "Hamas-style" tunnels beneath the Belarus–Poland frontier to funnel migrants into the European Union. Polish security officials quoted in the article would not confirm the claim but acknowledged detecting fresh subsurface disturbances during routine ground-penetrating-radar sweeps near Białowieża Forest. Warsaw’s Border Guard has already reinforced above-ground barriers with seismic sensors capable of picking up underground vibration. If tunnel activity is verified, Poland may invoke Article 28 of the Schengen Borders Code to prolong its internal border controls with Germany and Lithuania beyond the current April 2026 expiry date. For global-mobility teams, renewed controls could mean longer queues at terrestrial crossings used by cross-border commuters and haulage firms. Employers should advise staff holding Polish residence cards to carry proof of employment and housing, as ad-hoc identity checks inside Poland are likely if the security alert level is raised. The episode underscores how geopolitical tensions are reshaping Schengen travel norms. Companies with Belarus-based operations are already re-routing staff flights through Vilnius or Riga; a substantiated tunnel threat could see insurers increase premiums on travel policies covering eastern Poland.
