Two girls were killed when a wall collapsed on them at the Kennedy Road informal settlement in Clare Hills, Durban, on Monday afternoon.
The girls, 5 and 7, sustained major injuries and nothing more could be done for them by the time paramedics arrived around 16:00, said Rescue Care spokesperson, Garrith Jamieson.
A third girl was moderately injured in the collapse and rushed to hospital.
Rescue Care said the circumstances leading up to the wall collapse would be investigated by authorities on scene.
