A nationwide blackout has occurred in Cuba due to the collapse of the country's energy grid. This incident happened late on a Sunday and is the first blackout in August. The blackout follows three similar incidents in July, which have been challenging for the local population.

Cuba's energy infrastructure is under strain, partly due to a US oil blockade. Further details about the blackout are not available from the state utility company. For more information, readers can refer to the original report from CNN.
