Tanzanian Prime Minister Kassim Majaliwa has said the death toll from Sunday’s plane crash in Lake Victoria has jumped to 19, after the Precision Air flight with dozens of passengers aboard plunged into water while approaching the northwestern city of Bukoba.

Regional authorities and the airline earlier said that 26 survivors out of the 43 people on board flight had been pulled to safety and taken to hospital in the lakeside city in Kagera region.

A regional official said It was not immediately clear if the 19 victims included rescuers who drowned or whether the 48-seater aircraft had more people on board than previously disclosed.

Video footage broadcast on local media showed the plane largely submerged as rescuers, including fishermen, waded through water to bring people to safety.
