Zanzibar's opposition leader Seif Sharif Hamad on Tuesday slammed an electoral "farce" after he was released from detention, saying 10 people had been killed in violence on the islands ahead of Tanzania's polls. "How can you have an election were you have teargas everywhere and live ammunition? It is in no case a fair election, it is just a farce," said Hamad, of the ACT-Wazalendo (Alliance for Change and Transparency) party ahead of Wednesday's vote. fb/np/ri
