Lithuania is planning a mass evacuation of civilians in case of war, according to the Interior Ministry, as NATO members adopt measures against potential Russian attacks.

The Baltic States—Lithuania, Latvia, and Estonia—signed a January agreement to create a common defense line with anti-mobility infrastructure to bolster NATO’s eastern border with Russia and Belarus.

Lithuania’s Interior Ministry stated preparations to relocate a quarter of its 2.6 million population, prioritizing pregnant women, families with young children, and people with disabilities.

Vilnius Mayor Valdas Benkunskas highlighted measures such as developing shelters and installing warning sirens, Newsweek has reported.

In Latvia, anti-tank concrete pyramids, or “dragon’s teeth,” are being installed along the border with Russia as part of the Eastern Border Fortification and Counter-Mobility Plan approved in March.

These obstacles, first used in WWII, are designed to impede tank and mechanized infantry advances.
