South Africans are expressing shock over the murder of two toddlers whose bodies were found in a toilet in a township north of Johannesburg.

Angry residents in the Diepsloot area held violent protests on Tuesday after the bodies of the girls, who were two and three years old, were discovered. Local media say the crowd looted shops and burned tires in the streets. The area was quiet Wednesday.

Residents accuse police of failing to provide security for their community.

President Jacob Zuma's office is reporting a separate case of a young boy whose body, bearing marks of torture, was found in a field east of Johannesburg.

Zuma says in a statement that the gruesome incidents "do not belong to the society that we are continuously striving to build together."
