The High Court in Uganda's capital, Kampala, has sentenced a 25-year-old serial killer to 105 years in prison.

Musa Musasizi was sentenced on Wednesday after pleading guilty to the murder of three women said to be his girlfriends and a three-month-old girl who was the child of one of his victims.

He reportedly pursued romantic relationships with the women before sexually assaulting and killing them, then burning and disposing of their bodies, the court heard.

Justice Margaret Mutonyi said the long sentence was necessary to protect young women, including Musasizi's six-year-old daughter, the privately-owned NTV channel reported.

Musasizi had been arrested in March 2021 on suspicion of killing five women and an infant.

He was convicted for the murder of one of the women in July.

At that time, his lawyer asked the judge for mercy, saying that Musasizi, a former street child, had survived a difficult upbringing.
