* Ferry has capsized with no confirmed reports of deaths
* More than 200 killed in ferry disaster in September
STONE TOWN, Zanzibar, July 18 (Reuters) - A ferry with more than 280 people on board sank off the east African coast of the Zanzibar archipelago on Wednesday, but it was unclear whether anyone had been killed, officials said.
The ferry, MV Salama, set sail from the mainland Tanzania at around midday heading to Zanzibar, Tanzania’s semi-autonomous archipelago and a popular tourist destination.
“The ferry is bottom-up, and rescue operations are ongoing. So far we have not confirmed any deaths,” Said Khamis, a safety officer at the Zanzibar Port Corporation, told Reuters.
MV Salama, or peace in the local Swahili language, was carrying 250 adult passengers and 31 children, police said.
It was still unclear what caused the accident near Chumbe island, west of Zanzibar, police said.
The ferry is owned by a company named Seagull, which also runs a number of other ferries.
More than 200 people were killed when a crowded ferry sank in September off the coast of east Africa in the worst maritime disaster in the history of Zanzibar.
