Lithuania plans to build a 2-meter-high wire fence along its border with the Russian region of Kaliningrad, its interior minister said on Tuesday, amid continued tensions between Moscow and the Baltic states, which are members of NATO.

Eimutis Misiunas acknowledged that such a fence would provide little defense against a full-blown military assault but said it underscored Lithuanians' concerns about a more assertive Russia and could also help prevent lesser cross-border incursions.

"As we evaluate the geopolitical threats, the Russian geopolitical threats, Lithuanian politicians have expressed their will that we need to have a physical barrier with such a country (as Russia)," Misiunas told Reuters.
