A Ugandan police official says at least 10 people have died in a boat accident on Lake Victoria.
Police spokesman Emilian Kayima said late Saturday that police marine units had pulled 40 survivors from the water.
Initial reports suggest the boat cruise was carrying 120 people.
Mr Kayima said search and rescue efforts will continue overnight for others believed to be trapped under the water in the completely submerged boat.
He gave no details on the cause of the accident, which happened in Mpatta Sub-County in the Mukono District.
Police in Uganda confirmed on Twitter that 10 people have died in the boat accident.
Boat accidents are increasingly common on East Africa's major lakes including Lake Victoria, which is surrounded by Tanzania, Kenya and Uganda.
Over 200 people were killed in a Tanzanian ferry disaster in September, with officials saying it had been dangerously overcrowded.
