Residents of the South African city delight in rare snow day caused by a surge in humidity and cold temperatures

Residents of South Africa’s biggest city, Johannesburg, were stunned by the first snowfall in over a decade on Monday, with some children seeing snow for the first time.

Leak in informal settlement in Boksburg on outskirts of city may be linked to illegal mining, authorities say, as search continues for more casualites

At least 16 people, including three children, died when toxic gas leaked from a cylinder near Johannesburg, South African police have said. Emergency services said the leak appeared to be linked to illegal mining activities.

Emergency services initially announced that as many as 24 people might be dead in the Angelo informal settlement in Boksburg, a city on the eastern outskirts of Johannesburg. But police and Gauteng Province premier Panyaza Lesufi later said the number of deaths had been confirmed as 16 after a recount of the bodies. Police said the three children killed were aged one, six and 15. Two people were taken to the hospital for treatment, police said.
