The electrical grid across Cuba failed on Sunday, marking the fourth time this month the entire country has lost power. These outages follow a series of three similar nationwide collapses that occurred throughout July. The nation is currently grappling with severe fuel scarcity, which has been exacerbated by a US-led oil blockade. Cuba's fuel supply issues intensified after the US detained Venezuelan President Nicolas Maduro in January, effectively halting oil shipments from Venezuela to the island.
