A two-year-old girl burnt to death on Thursday after her mother left her locked in a shack with a paraffin stove on, emergency management services said.
Spokesperson Malcolm Midgley said the girl's mother had visited neighbours at 8am. When she returned, her shack was engulfed in fire.
"When firefighters got to the scene, the shack had already collapsed and the baby was dead," he said.
It was not yet clear whether the mother would be charged.
Midgley said the Alexandra toddler's death was the third fire-related death in two days, all in shack fires.
On Wednesday, two children were burnt to death in separate incidents in Johannesburg.
A boy, 8, was burnt to death while sleeping with his parents in a shack in Lombardy East and a two-year-old toddler was killed when a shack caught fire in Ivory Park. - Sapa
