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

Tropical Storm Oscar doused Cuba on Monday, three days after a massive power failure plunged more than 10 million people into the dark as the island worked to restore its decades-old power grid.

The fourth such failure in 48 hours raised fresh doubts about a quick fix on an island already suffering from severe shortages of food, fuel and medicine.

Cuba's government is reportedly working to reestablish electrical service across the country after the national grid collapsed for the second time since midday Friday.

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.
