At least 126 people have died and 40 others have been rescued after a ferry carrying hundreds of people capsized in Lake Victoria, Tanzania.
MV Nyerere sank on Thursday afternoon on its way to Ukara Island from Bugolora Island, in Mwanza.
The vessels is believed to have had hundreds of people on board.
This is what we know about the latest maritime tragedy so far:
Brisk business: It was a market day in Bugolora and passengers on MV Nyerere were aplenty.
Passenger numbers: It is unclear how many people were on board since the ticketing officer was among those perished. The officer's records and machine have not been found yet. Sources say the 100-capacity ferry could have had more than 300 people on board.
"There were more than a hundred passengers on board when the ferry sank. It is feared that a significant number have lost their lives," said George Nyamaha, head of Ukerewe District Council in Mwanza.
Cargo: The vessel is believed to also have carried cargo above its capacity. Among the cargo were bags of cement, sacks of maize, and traders' merchandise.
Vessel: The Tanzania Electrical, Mechanical and Electronics Services Agency (Temesa), which operates ferry services, said the MV Nyerere did not have any mechanical problems because heavy maintenance had been carried on it in recent months including overhauling two engines.
Disaster: According to Temesa, the vessel toppled over as it prepared to dock at Ukara Island. It is believed that it toppled over when crowds on board moved to one side as it docked. WATCH VIDEO
Search: Rescue efforts are led by the Tanzanian Navy assisted by locals and private companies.

As at Friday afternoon, 126 bodies have been found, Issac Kamwelwe, the Minister for Works, Transport and Communication, said, adding that the rescue exercise will be concluded later Friday.
