Electricity has been restored to half of Havana, the Cuban capital's power company reported Monday, four days after the start of a nationwide blackout that the authorities have struggled to address.The government has said that electricity is expected to be restored to most of the country by the end of Monday.

Cuba entered a third day without electricity after another outage Saturday evening set back efforts to restore power on the island, underscoring the challenges posed by decades-old, poorly maintained infrastructure.

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.
