Zanzibar: Tanzania's semi-autonomous Zanzibar archipelago went to the polls on Sunday amid tight security in a re-run of disputed elections that have been boycotted by the main opposition party.
Zanzibar's electoral authority annulled a previous ballot on Oct. 25 on grounds of fraud. The opposition Civic United Front (CUF) says it won those election hs and it had warned of violence on the Indian Ocean islands if Sunday's ballot went ahead.
