Cuba took another step on Sunday toward the end of the Castro era, with millions of residents placing paper ballots in cardboard boxes for ward delegates to municipal assemblies.

The vote comes the day after the first anniversary of revolutionary leader Fidel Castro's death and precedes another election early next year for provincial and national assembly deputies.

The new national assembly, where 50 percent of the deputies must be ward delegates elected on Sunday, is expected on Feb. 24 to select a new president to replace Raul Castro, Fidel's 86-year-old younger brother, who has said he will step down after serving two five-year terms.
