The Baltic Sea region is on high alert following power cable, telecom and gas pipeline outages between the Baltics and Sweden or Finland. All were believed to have been caused by ships dragging anchors along the seabed following Russia’s invasion of Ukraine.

The three Baltic states disconnected their electricity systems from Russia's power grid on Saturday, the region's operators said, part of a plan designed to integrate the countries more closely with the European Union and boost security.

Formerly part of the Soviet Union, the staunch supporters of Ukraine switched off the Russian grid's transmission lines on Saturday.

More than 30 years after leaving the Soviet Union, Estonia, Latvia, and Lithuania will join the EU's grid.

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.
