Seven of the victims were children, the youngest a 1-year-old, according to an emergency services spokesperson. Emergency crews expected to find more victims as they worked their way through the building, a process slowed by the conditions inside. Mulaudzi said the death toll was likely to increase and more bodies were likely trapped inside the building.
