A ferry carrying at least 250 people has sunk off the coast of Tanzania near the island of Zanzibar.
Rescuers have been at the scene and many people are still missing.
Back in September more than 200 people died when a crowded ferry sank off the coast of east Africa, that was the worst maritime disaster in the history of Zanzibar.
