Cuba plunged into darkness amid nationwide blackout

Cuban authorities scrambled Sunday to restore power to the island after the second nationwide blackout in less than a week, as the grid struggles due to an aging infrastructure and a US oil blockade. Some parts of Havana began to have power again, but others were still dark early Sunday, a day after the energy ministry reported a "total disconnection" of the national electric system in the country of nearly 10 million people.
