Cuba's power grid has ground to a halt for a second time in as many days, leaving 10 million on the island without power and the Caribbean island in a growing sense of crisis.

Cuba’s electrical grid went down Friday after one of the island’s major power plants failed, a day after a massive blackout swept across the Caribbean island and with no official estimate for when service will be restored.

Millions of Cubans awoke on Sunday to find their homes still without power after another partial grid failure overnight, deepening a crisis that has raised questions over the viability of the government's efforts to reestablish electrical service.

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.
