The Baltic states are set to sever ties with Russia's power grid that date back to the 1950s, and instead integrate further with the European Union, as the suspected sabotage of subsea cables has spurred efforts to strengthen regional security.

The Baltic states of Lithuania, Latvia, and Estonia are bracing themselves for possible retaliation as they decouple from Russia’s power grid this weekend.

Estonia, Latvia, and Lithuania, three small countries in northern Europe, are about to make a major step in cutting ties with Russia. These countries, which were once part of the Soviet Union, have relied on Russia to manage their electricity grid for many years.
