Polish authorities discovered a tunnel from Belarus into Poland used to funnel illegal immigrants, marking a new phase of border pressure.
On September 20, 2025, Polish authorities uncovered a tunnel crossing the border from Belarus into Poland used for illegal immigration purposes. This discovery reveals a new tactic described as a 'new Iron Curtail,' indicating deliberate efforts by the Belarus regime to push unauthorized migrants through covert border crossings into Poland. The incident underscores rising hybrid pressure on Poland’s border security and migration management challenges. The event further aligns with ongoing tensions and manipulation of migration flows in the region. No specific numbers of migrants or tunnel dimensions were disclosed in the available information.
Confidence: High
The event explicitly describes Belarusian (regime) facilitated illegal immigration via a tunnel into Poland as an active hostile hybrid tactic, qualifying as aggressor activity without mentioning any defensive preparations by Poland in this specific report.
