A five-year-old boy and his mother, along with a 92-year-old man, are among the six people dead after Hurricane Oscar hit the coastal city of Baracoa and nearby areas in the eastern province of Guantánamo in Cuba as a Category 1 storm on Sunday, bringing heavy rains and flash flooding in a region that has been without electricity since Friday.

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.
