Lithuania, Latvia and Estonia are still connected to Russia's electricity grid, but that's going to change soon in another sign of their confidence in the EU. With the move they turn the page on their Soviet past.

Nearly 3 1/2 decades after leaving the Soviet Union, the Baltic countries of Estonia, Latvia and Lithuania this weekend will flip a switch to end electricity-grid connections to neighboring Russia and Belarus.

Lithuania has warned of potential risks linked to the change, including possible cyber attacks, which will happen Saturday morning.

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.
