Latvia has begun installing concrete anti-tank barriers called “dragon’s teeth” along its border with Russia, while NATO prepares to assign a new army corps to defend Estonia and Latvia in the event of a conflict with Moscow. Latvian public broadcaster LSM reported on Thursday that Latvia’s National Armed Forces are placing heavy concrete pyramids in several rows along sections of the Russian border, as a part of the Baltic Defence Line being developed jointly by Estonia, Latvia and Lithuania.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. “This is necessary primarily to improve the security of the border checkpoint. About five years ago, we had an incident when a car from Russia broke through the existing barriers. Installation of barriers will help prevent unauthorized travel. Also, the installation of the gate will help better control the situation on the bridge, for example, in the event of a flow of migrants,” the Head of the Narva Border Center Antti Eensalu said. “Dragon’s teeth” are concrete barriers that weigh around 1.5 tons, and are about 10 meters wide, sectioned in three rows. The line will eventually include anti-tank ditches running roughly 450 kilometers. In late August 2025, Lithuania placed similar obstacles at unused Šumskas, Lavoriškes, Latežeris, and Raigardas checkpoints on the Belarus border, and at Romaniškes on the Russian (Kaliningrad) border.
