Photos emerging from Cuba show not only the unrest, but residents continuing to lives their lives even amid the indefinite power outages.

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.

The Cuban people have been left in the dark after their nation's electrical grid collapsed Friday. "It was really frustrating because we don't know how long it will last," Omar McKenzie, a Cuban resident in Havana told CBS News Miami.

Cuba’s electrical grid went offline after one of the island’s major power plants failed, the energy ministry said. Authorities on Friday said all classes have been suspended and that they will shut down some state-owned workplaces.

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.
