By Agence France-Presse Tanzania declared the whole nation was in mourning Sunday as the first dozen bodies were buried from a devastating ferry capsize on Lake Victoria that left people 224 dead. Prime Minister Kassim Majaliwa led "national funerals" on the island of Ukara, where the MV Nyerere had been coming in to dock on Thursday (AFP / MANILA BULLETIN) Prime Minister Kassim Majaliwa led "national funerals" on the island of Ukara, where the MV Nyerere had been coming in to dock on Thursday. He spoke of "great mourning by the whole nation" as the first coffins were placed in individual graves, many of the victims unidentified. The remainder of the dead were to be buried later or taken away by families wishing for privates funerals. The prime minister said a memorial would be built on Ukara. AFP/File / STRINGER The ageing ferry, whose hull and propellers were all that remained visible above water Hopes had faded of finding any more survivors three days after the disaster, even after rescuers pulled out an engineer on Saturday who had holed up in an air pocket in the upturned vessel. But Majaliwa said divers would continue the grim search in the waters around the boat. The ferry would also be refloated. He updated the death toll to 126 women, 71 men, 17 girls and 10 boys. Just 41 people survived. 'Overloading' blamed for tragedy Transport Minister Isack Kamwelwe said 265 people had been on board the ferry, which had an official capacity of around a hundred passengers. The prime minister said initial investigations suggested overloading was one of the causes of the accident. "We have already arrested all those people in charge of operating and supervising the MV Nyerere. Questioning has begun," he said. A broader commission of inquiry into the disaster would also be set up, Majaliwa added. Witnesses told AFP that the ferry sank when passengers rushed to one side to disembark as it approached the dock. Others blamed the captain, saying he had made a brusque manoeuvre. The Tanzanian presidency announced on Sunday evening that the inquiry had been "entrusted to the defence and security authorities". Transport minister Kamwelwe said on Saturday that 172 of the bodies had been identified by relatives.
