Zanzibar's main opposition party has claimed its candidate won a presidential poll that triggered three days of violence in the semi-autonomous Tanzanian islands.
"Despite the massive attempts at rigging, our returns indicate our presidential candidate has won with a very small margin," said Ibrahim Lipumba, national president of the opposition Civic United Front (CUF).
He said 50.63 per cent of the votes from Sunday's poll backed Seif Sharif Hamad, CUF candidate for the Zanzibar presidency, compared to 49.37 per cent for the ruling party's candidate.
