SANTO DOMINGO, (Reuters) – At least three people  were killed in shootings in the Dominican Republic on Sunday as  voters cast their ballots in congressional and municipal  elections, authorities said.

The head of an Organization of American States election  observers’ mission said voting in the small Caribbean state had  generally gone ahead normally, despite what he described as  isolated incidents of violence.

More than six million voters were eligible to elect 32  senators, 178 deputies and 155 mayors as well as several  thousand municipal government representatives.
