Millions of people in Cuba remained without power Saturday after a failure of the nation’s electric grid left the island in the dark the previous night.

Cuba’s power grid collapsed Friday night, triggering a nationwide power outage and plunging its more than 10 million people into darkness.

Cuba's capital Havana plunged into darkness for a second night on Saturday as efforts to restore power proceeded in fits and starts, with setbacks slowing progress and leaving several million still without electricity across the island.
