At least 16 people, including three children, have been killed by a leak of toxic nitrate gas in South Africa, police and local government authorities said.
Emergency services initially announced as many as 24 people might be dead in an informal settlement in Boksburg, a city on the eastern outskirts of Johannesburg, but police and Gauteng Province premier Panyaza Lesufi said the number of deaths had been confirmed as 16 after a recount of the bodies.
