Cuba had four electric grid collapses since Friday, and most of the country remains in the dark as slow progress is made to restore power.

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.

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.
