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.

After the disconnection plans were announced, propaganda campaigns cropped up on social media and in printed leaflets in city streets that issued fake-news warnings about blackouts, severe energy shortages and sky-high energy bills for consumers.

The severing of electricity ties to oil- and gas-rich Russia and switching to European grids is steeped in geopolitical and symbolic significance.
