The Cuban government on Monday announced that the Latin American island nation was subject to a nationwide blackout.

The Cuban Ministry for Energy and Mines said that there has been a “total disconnection” from the electricity grid.

Cuba has been suffering long blackouts as US President Donald Trump’s administration blocks Venezuelan oil shipments to the island. Venezuela had been Cuba’s top supplier of oil.

The US operation to arrest Venezuelan President Nicolas Maduro in January was a significant blow to the Cuban government. Since then, Trump has backed acting President Delcy Rodriguez and oil deliveries to Cuba have been halted.
