DAR ES SALAAM (Reuters) - Four people have been charged with causing the deaths of more than 200 people when a crowded ferry sank last week in Zanzibar, local media reported on Saturday. The captain of the MV Spice Islander I ferry, Said Abdallah Kinyanyite, 58, who remains missing, was charged in absentia at the Zanzibar High Court on Friday. Authorities said they could not confirm whether or not the captain had drowned in the accident in the early hours of September 10.
