A national blackout has occurred in Cuba due to the collapse of the electrical grid. This incident happened on a Sunday night, as announced by the state electricity company on social media. The blackout is the first one in August and follows three similar incidents in July.

Cuba's energy infrastructure is being tested by a US petrol blockade. Further information on the blackout is not available from the state electricity company, but more details can be found through CNN or other news sources, such as KVIA ABC-7.
