An islandwide blackout hit Cuba on Monday as the country''s fuel reserves dwindle and its electric grid continues to crumble. The blackout in the country of nearly 10 million people was reported by the state-run Electric Union, which said on X that the cause is under investigation. The Ministry of Energy and Mines wrote on X that it has activated protocols to restore electricity.

Fuel has been running out across Cuba since January, when US President Donald Trump threatened tariffs on any country that sells or provides oil to the island, deepening the island''s ongoing economic and financial crisis. Public transportation has largely been halted, and officials have cancelled tens of thousands of surgeries.
