Four children have been "brutally stabbed and killed" at a school in the Ugandan capital, Kampala, the police have said.

"The suspect has been apprehended, and the motive behind the killings is still under investigation," Uganda's police force added in a brief statement on X.

The school has been named as the Ggaba Early Childhood Development Program school in the capital's Makindye Division.

More details will be provided later, it added.

Uganda's Daily Monitor newspaper is quoting local residents as saying that the suspect posed as a parent to get into the school and then after talking to the administrator attacked the children. The victims were between the ages of two and three, the newspaper adds.
