Hurricane Oscar, which slammed into Cuba over the weekend during a major power outage, caused the deaths of six people, AFP reports.
The lights went out in the communist country of 10 million people on October 18 after the collapse of the country's largest power plant crippled the entire grid.
By the afternoon of October 21, nearly 90 percent of consumers in Havana - home to about two million people - had electricity again, the capital's power company said.
However, authorities say many residents outside Havana remain without electricity.
Cuba was still plunged into darkness on 20 October when Hurricane Oscar made landfall in the east of the country as a Category 1 storm, causing several deaths and damage.
"Unfortunately, according to preliminary information, six people have died," President Miguel Díaz-Canel said in a televised address.
He said the storm had caused serious damage in the eastern province of Guantanamo.
As it moved inland, Oscar weakened to a tropical storm but was still expected to bring "significant, life-threatening flash flooding along with mudslides," the US National Hurricane Center warned.
Roofs and walls of houses were damaged and power poles and trees uprooted, state television reported. | BGNES
