In 2026, Lithuanian border guards observed a new method of illegal entry involving tunnels dug under the Lithuania-Belarus border. Rustamas Liubajevas, head of the State Border Guard Service (VSAT), confirmed about 10 tunnels have been detected this year, with the longest tunnel detected inside Lithuanian territory measuring approximately 25 meters long. These tunnels are reportedly started on Belarusian territory, dug under the borderline, and extended into Lithuania, sometimes up to 30-40 meters in total length. The tunnels are often dug 8 meters deep and reinforced with wood. VSAT suspects that Belarusian regime officials assist or facilitate this tunneling activity, indicating state participation in organized hybrid pressure on Lithuania's border. Lithuanian authorities employ equipment, including scanning devices borrowed from Polish border guards, to detect tunnel digging activities underground. Migrants primarily come from Afghanistan, Pakistan, and African countries, with African migrants increasingly using routes through Latvia. Since the start of the Belarus-related migration crisis in 2021, about 25,600 illegal migrants have been stopped at the Lithuanian border. The Belarusian regime is also noted to sometimes damage physical border barriers, particularly between Belarus and Latvia.
