JOHANNESBURG – At least 16 people died in an informal settlement near Boksburg east of Johannesburg following a suspected gas leak, the head of the provincial government said on Wednesday after a recount of fatalities.

South Africa's Gauteng Province Premier Panyaza Lesufi told reporters as he visited the scene that investigations were underway to determine what type of gas was involved.

The bodies were scattered over the area, Lesufi said, adding that the youngest victim was a one-year old.
