Millions of Cubans faced a third consecutive day without power as a hurricane loomed over the island nation Sunday. Sixteen percent of the country had power restored Saturday but attempts to restore it more widely failed overnight,

Fidel Castro once called Cuba’s power plants “prehistoric.” But the country still relies on them, contributing to the longest blackout since the collapse of its former patron, the Soviet Union.

Cuba’s government says some electricity has been restored on the island after one of the country’s major power plants failed and left millions without electricity in an outage that started two days earlier.
