Cuban officials reported a complete island-wide blackout affecting the country's 11 million residents on Friday, as the nation continues to struggle with severe energy and economic crises.

The Ministry of Energy and Mines announced on social media platform X that there had been a "complete disconnection" of the country's electrical system and said authorities were investigating the cause of the outage.

President Miguel Díaz-Canel had warned earlier on Friday that Cuba had not received oil shipments in more than three months. He said the country was currently operating on solar power, natural gas and thermoelectric plants to meet its energy needs.

The latest blackout follows a massive power outage that occurred over a week ago, which affected the western portion of the island and left millions of people without electricity for an extended period.

Cuban officials have attributed the country's energy difficulties to what they describe as a U.S. energy blockade. In January, President Donald Trump issued warnings of potential tariffs against any country that would sell or provide oil to Cuba.

The blackout represents the latest challenge for Cuba as it faces mounting economic pressures and infrastructure problems that have left essential services vulnerable to widespread disruptions.
