Dominicans frustrated by slow election results kill six - official

SANTO DOMINGO (Reuters) - Six people were shot dead at voting centres after polls closed in Dominican Republic's presidential election, the electoral chief said on Monday, blaming the clashes on delays to results stemming from parties' insistence on manual vote counting.

Roberto Rosario, who heads the Caribbean nation's electoral board, said tensions rose in the hours after polls closed on Sunday evening, as activists for different parties grew frustrated with the slow pace of the vote count.
