Cuba's power-grid operator said it had restored electricity to parts of the capital Havana on Monday following a fourth major grid failure in 48 hours, while Tropical Storm Oscar lashed the island's eastern end.

Cuba's power-grid operator said it had restored electricity to most of the capital Havana on Monday even as Tropical Storm Oscar lashed the island's eastern end, downing trees and power lines.

Many Cubans waited in anguish Sunday as electricity on much of the island had yet to be restored days after an island-wide blackout. Their concerns were also raised as Hurricane Oscar made landfall in the southeastern Bahamas and was heading toward their country.
