HAVANA, Cuba—Cubans were gradually getting power back on Wednesday, after the third nationwide power outage in less than 10 days, the national electricity company said.

The communist island was already struggling to keep the lights on before US President Donald Trump cut off its oil supplies in January, depleting the dwindling supply of fuel for its power plants.

The national power grid went offline at about 11:05 am (1505 GMT) on Tuesday, according to the state-run UNE electricity company, leaving the country’s 9.6 million inhabitants without power.
