The girls, aged between eight and ten, are believed to be siblings.
Reports say they bought snacks at a local tuck shop in Ramosadi village.
The girls died on Friday after apparently complaining of stomach pains.
Provincial police Spokesperson Adel Myburg says, “Two girls got sick at a local school; one is eight years old and the other is ten years old. The school took them to the local clinic; unfortunately, the eight-year-old passed away. According to the initial information received, the elder sister, who is ten years old, indicated that they bought snacks at a house in Ramosadi village. After eating the snacks, they apparently experienced stomach cramps and aches when they got to school.”
