Polish border guards have discovered a hidden tunnel used by migrants to cross the border from Belarus into Poland and the EU. The entrance to the tunnel was located during a routine patrol, and authorities followed it into Belarusian territory. Dozens of individuals are believed to have utilized this clandestine route to circumvent official border controls. This discovery highlights ongoing efforts to illegally enter the European Union via the Poland-Belarus border. The tunnel represents a new tactic employed by smugglers facilitating unauthorized migration. Polish authorities are investigating the extent of the operation and working to prevent further breaches. This incident underscores the challenges faced in securing the EU's eastern border.
