Cuban President Miguel Diaz-Canel confirmed the preliminary death toll after Oscar made landfall as a Category 1 hurricane but provided no details of how the deaths had occurred.

Cuba's power grid collapsed on Sunday evening for the fourth time in two days, plunging much of the island nation into darkness as Hurricane Oscar made landfall in eastern Cuba as a Category 1 storm.

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.
