Zimbabwe election 'free and fair', say AU observers

The African Union observer mission in Zimbabwe has declared that the presidential elections were "free, honest and credible".

This assessment stands in stark contrast to claims made by the Zimbabwe Election Support Network, the largest observer group in the country - questioning the credibility of the process and calling it "compromised".

So far President Robert Mugabe's party has claimed victory in the election, which has been rejected as a "huge farce" by Prime Minister Tsvangirai.
