The collapse follows nationwide blackouts last year that plunged Cuba's frail power-generating system into disarray.

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.

The collapse plunged the island nation of more than 11 million people into total darkness. It's the latest in a series of failures in the country's creaking, soviet-era infrastructure.
