Johannesburg - A man was burnt to death when his shack caught fire in Wynberg, south of Johannesburg, on Saturday, emergency services said.
Three other shacks were also destroyed, spokesperson Robert Mulaudzi said.
The fire, which started around 22:00, was suspected to be caused by an unattended paraffin stove.
"We want to advise communities to make sure that paraffin stoves [and] candles are supervised when in use to avoid devastating fire incidences like this one," Mulaudzi said.
Fifteen shacks were destroyed earlier on Saturday around 0:00, by a fire in Msawawa informal settlement, in Kya Sands, north of Johannesburg.
No injuries were reported. The cause of the fire was still being investigated.
