The repeated failure of the power grid and a hurricane that has swamped the island’s eastern end has many Cubans fed up, posing a challenge to the Communist government.

Hurricane Oscar left six people dead after hitting Cuba over the weekend during a major power blackout, authorities said Monday, as electricity was restored to most of the capital.

Cuba's capital remained largely paralyzed on Monday and the rest of the island braced for the fourth night of a massive blackout that has generated a handful of small protests and a stern government warning that any unrest will be punished.
