Cuba’s power grid collapsed for the third time this month, plunging the nation into darkness. The blackout, traced to a failure at the Nuevitas thermoelectric plant in Camaguey province, follows two earlier outages within a week.

The Cuban Electric Union reported that microsystems were restored across all territories by Sunday morning. However, the government attributes the recurring failures to decades-old infrastructure and ongoing US sanctions.

Cuba produces less than half the fuel it needs. Since February, the island has not received oil from foreign suppliers, including Venezuela-where President Nicolas Maduro and his wife were detained in early January, halting critical shipments.

The US trade embargo, extended under Donald Trump’s executive order last month, remains in effect since 1962. The UN Human Rights Office has denounced the policy as a violation of international law.

Social media footage from Havana shows protests, with citizens demanding liberty after recent blackouts.
