Rescue and recovery missions search for the bodies of dead passengers after a cruise boat capsized in Lake Victoria off Mukono district, Uganda November 25, 2018.
The boat, which was occupied by revellers on a cruise, capsized in Mpatta Sub-county in Mukono District, Uganda.
"The boat was overloaded and secondly there was bad weather", Onyango told Reuters.
It has been reported that some of the rescuers have died.

Witnesses who were there on Saturday night said they heard people calling for help as they tried to stay afloat and others tried to swim ashore.
Though Police spokesman Emilian Kayima said late Saturday that police marine units had pulled 40 survivors from the water, he however disclosed that 10 people have already been confirmed dead.
There was a party going on aboard the boat, with loud music, at the time of the accident, Museveni said.
The police spokesperson for the Mutima rescue and recovery operation, Ms Zurah Ganyana, said their officers engaged the group telling them the boat had been grounded for three months and refurbishments had been hurriedly done, but they attempted to turn rowdy.
On Sunday, President Yoweri Museveni blamed the accident on overloading, saying the boat was carrying more than its capacity of 50.
Prince David Wasajja, a brother of Buganda King Kabaka Ronald Mutebi, was on the boat, along with singer Iryn Namubiru and rapper The Mith, according to reports.
"We suspect the mechanical condition of the boat and the weather contributed to the sinking".
Ferry accidents are not uncommon on the lake and the number of fatalities is often high due to a shortage of life jackets and the fact that many local people can not swim.
The boat had gone about half its journey when the captain noticed the hull was "taking in water very quickly from welded spots", said Henry Ategeka, Uganda's principal marine inspector, citing findings from a preliminary investigation.
The boat's passengers, in a party mood halfway through their journey, likely panicked when the vessel started to sink, he said.
