At least 29 people are now known to have died after a cruise boat carrying party revellers capsized on Lake Victoria, Ugandan police say.

The vessel was carrying close to 100 people when it sank on Saturday near Uganda’s capital, Kampala.

Ugandan media named a number of well-known people said to be on the boat, adding that the prince of a traditional kingdom had survived

Scores of people died when a ferry sank on the lake off Tanzania in September.

Saturday’s accident occurred off Uganda’s Mukono district.

Deputy police spokesman Patrick Onyango told Reuters news agency: “The boat was overloaded and secondly there was bad weather.”

More than 20 people have been rescued from the water, police say, but an unknown number remain missing.

Ugandan media said musical artist Iryn Namubiru also survived.

A number of other popular artists and socialites were believed to be on board.

The boat was reportedly hired out for weekend parties.

Local officials said two small fishing boats that came to the rescue also became overloaded and sank.
