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.

Cubans in the eastern provinces of Holguín and Guantánamo braced for a direct hit by Hurricane Oscar on Sunday afternoon. As the Category 1 hurricane made landfall near Baracoa, a coastal in city in Guantánamo province, around 5:50 p.m., most of the country still had no power.

We haven’t had electricity for three nights,” said one Cuban protestor, amid widespread blackouts. Authorities said the outage stemmed from increased demand but residents say this is just the latest issue in a series of problems with electricity.
