Cuba has suffered a massive power outage affecting Havana and the country’s provinces that has left millions in the dark.

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

Cuba's national electrical grid collapsed late on Friday, the country's Energy and Mines ministry said, leading to widespread blackouts in the capital Havana and across the Caribbean island nation. Energy ministry officials said an electrical substation in Havana failed around 8:15 p.
