Lithuanian border guards say they have discovered tunnels that migrants are using to enter Lithuania from Belarus. According to the reports, the tunnels are part of efforts to carry people across the border illegally, and the authorities have drawn attention to the possible broader context behind the crossings. Analysts cited in the coverage interpret the tunnel system as a potential tool for destabilisation, suggesting it could be used to increase pressure on Lithuania and strain border security. The reporting frames the tunnels as evidence of organised attempts to bypass controls, rather than isolated incidents. Authorities describe the discovery as raising suspicion toward Minsk, reflecting concerns about the role Belarus may play in facilitating or tolerating such activity. The sources do not provide additional verified details on who is responsible for building or operating the tunnels, but they indicate that the findings are being used to support Lithuanian assessments of the situation along the border. The developments highlight ongoing tensions in the region and continued efforts by Lithuania to secure its frontier.
