A power outage has struck the entire island of Cuba on, the energy ministry said, in the second nationwide blackout in less than a week as its grid struggles under a US oil blockade.

March 17 (UPI) -- A magnitude 5.8 earthquake struck eastern Cuba early Tuesday, hours after the island's national power grid collapsed, leaving nearly the entire country without electricity and compounding an already severe economic and social crisis.
