Cuba's electrical grid collapsed again on Sunday, the fourth such failure in 48 hours, with a hurricane making landfall to compound the island's misery and threaten further havoc on its decrepit infrastructure.

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.
